How are you with cleaning or replacing filters? I do not mean so much your personal skillset to do it, but more your consistent initiative to get it done. When you think about it, cleaning or replacing filters has some place in all of our lives, whether we are the ones directly doing it or not.

Filters are everywhere. You have oil filters and air cabin filters for our cars, water filters, home air filters, even lint filters for our dryers. You have vacuum filters, coffee filters, and furnace filters. Even for those tea drinkers among us, the tea bag itself is a filter. Depending on the type of filter and its use, filters need cleaning or replacing often because they capture dust and debris, used grounds or leaves, chemicals and compounds, gunk and grease harmful for engines, lungs, or stomachs.

But, in addition to physical filters, there are also spiritual filters. If James expresses that alongside visiting orphans and widows in their affliction, part of a pure and undefiled religion before God is to keep oneself unstained from the world, then there is certainly a need of a clean spiritual filter. The LORD has given us what we need in this by uniting us by grace through faith to Jesus and declaring us forgiven and cleansed in Him. He has also given us His Holy Spirit. But there is a relational sense of walking in step with the Spirit, of growing in the likeness of Christ, of walking in a manner worthy of the calling to which we’ve been called by God. In light of this, how do we keep our spiritual filters cleansed and renewed from the worldly, toxic grime?

First, let’s identify a few deadly ways the world can infect us without utilizing God’s means of keeping us spiritually filtered and clean.

• Fatalism- Focusing on the world as the hopeless mess it is and us as hopeless sinners, and believing no good or change will ever come to it or us.
• Cynicism- Thinking that everyone is in it for themselves and motivated by greed and power. No one can be trusted.
• Overtly focusing on entertainment and distraction, consuming and wasting our lives with things that are eternally worthless.
• Idolatry in all forms, but especially to self, tribe, and sex.

How do we resemble Christ more and more, and this present form of the world that is passing away less and less?

This, and the question before, are big questions of sanctification and perseverance that the Bible speaks to in many places. I believe Paul has a helpful part of the answer for us today in Ephesians 1, starting in verse 15.

To give some brief background, Ephesians was written to the group of believers in the major city of Ephesus and likely other groups of believers in nearby towns and cities as well. Ephesus was a port city on the western coast of what is now modern-day Turkey. Paul wrote this letter while in prison for Christ in Rome towards the end of his life (likely AD 60-62), and sent it by his faithful minister and brother-in-Christ Tychicus. So far in the letter, he has briefly greeted believers and then pens an astounding section of praise to God for His sovereign election and adoption of His people in Christ and the sealing by the Spirit- all to the praise of His glory. This is where our section begins in verse 15.

So getting back to the issue at hand, what does Paul model for us as he’s locked up in prison that would help us keep our spiritual filters unstained from the world’s toxic grime? Not surprisingly for us in this prayer-themed year, the answer Paul models is a prayer. And this prayer starts, fittingly for this time of year, as a prayer of thanksgiving.

“15 For this reason, because I have heard of your faith in the Lord Jesus and your love toward all the saints, 16 I do not cease to give thanks for you, remembering you in my prayers, 17 that the God of our Lord Jesus Christ, the Father of glory, may give you a spirit of wisdom and of revelation in the knowledge of him, 18 having the eyes of your hearts enlightened, that you may know what is the hope to which He has called you, what are the riches of His glorious inheritance in the saints, 19 and what is the immeasurable greatness of His power toward us who believe, according to the working of His great might 20 that He worked in Christ when He raised Him from the dead and seated Him at His right hand in the heavenly places, 21 far above all rule and authority and power and dominion, and above every name that is named, not only in this age but also in the one to come. 22 And He put all things under His feet and gave Him as head over all things to the church, 23 which is His body, the fullness of Him who fills all in all.

Notice, Paul’s thanksgiving is not over his imminent release from imprisonment or worldly comforts. His prayer of thanksgiving from prison for the Ephesian people is for two specific reasons:

1. 1. Their faith in the LORD Jesus
   2. Their love toward all the saints

Two quick observations.

1. In the midst of Paul’s personal suffering, he is thankful to God for evidence of Christ’s saving work in other’s lives. He is Christ and kingdom-centered and others-focused.
2. He’s not ceasing in prayers of thanks to God for them, continually remembering them. Most of us know seasons of prayer for others, but sometimes people in my own life people fall off my radar. I’m not suggesting we have a prayer list that only grows and involves every person on it getting daily prayers. I do gently ask though- who are those people (specifically believers) we know God has placed personally in our lives and called us to pray consistently for whom we haven’t prayed for in quite a while? I’d encourage you to pause even now, or as you finish reading this, to lift that person up to God and consciously bring them back into your regular time of prayer.

At this point, in verse 17, Paul gets specific in what prayer for those for whom he is so thankful looks like. He asks 3 things. Now, I don’t know about you, but the content of these prayers are much different than the healing, comfort, safety I’m used to running through for people. These things aren’t wrong to pray, but consider the 3 prayer points Paul mentions:

1. That God the Father would give them a spirit of wisdom and revelation in their knowledge of Him.
2. So that with their hearts now enlightened they would know 3 things:
   1. The hope to which He has called them
   2. The riches of His glorious inheritance in the saints
   3. The immeasurable greatness of His power toward us who believe
3. A focus on the Gospel and who God has made Christ Jesus to be.
   1. Jesus is the One the Father has raised from the dead and seated alone at His right hand.
   2. Christ Jesus is far above all rule and authority and power and dominion, and above every name that is named in this present age, and the age to come.
   3. All things have been put under Jesus’ feet and He has been made the Head over all the Church, His body, and He fills all things everywhere.

So what is Paul’s help for us to keep our spiritual filters unstained from the world?

• To put your focus on Christ and give thanks to God for how you’re clearly seeing the Spirit of Jesus at work in believer’s lives.
• To continually lift up believers like this in prayer and share openly with them the way you’re encouraged by God’s work in them and work in others.
• To pray specifically that God would grant believers to experience a spirit of wisdom and revelation of their knowledge of God
• That through this greater understanding they’d experience hope and they’d ponder more with joy the inheritance we’re running to that nothing in this world can touch or compare
• To have a better understanding and knowledge of God’s great power- the same power that raised Jesus from the dead, seating Him above all others for all-time, who is now directing His church to expand

This is a model of prayer by Paul that we can use as a filter to remain unstained from the world. Prayer like this transforms our perspective from worldly to eternal.

When we were in Turkey, just before seeing Matthew, Kailie, and the boys, we stayed a night in Istanbul and visited the Hagia Sophia. This building was built in 537 AD. At the time it was not only the largest cathedral in the world, but the largest building as well. It became one of the centers for the Christian faith for hundreds of years. Great sadness welled up in me going inside the building with Katie and the boys though. In the 1400s, Istanbul was taken over by the Ottoman Turks. So for the better part of the last 500 years, Hagia Sophia has served as a mosque. Within 15 minutes of entering the building, everyone was quickly forced to exit and the Muslim cry for prayer soon followed. With all the building had symbolized, it just felt like such a loss. There was a thought of “this is what it is to be conquered”.

Though I was there to be an encouragement for Matthew, I shared what I’d felt being in that place with him the next day. Not only does God use prayer and his Word to clean and replace our world-contaminated filters, He uses His people as well. Matthew reminded me that night that we’re not to the end of the story yet. He also said, if you’d told Christians who worshipped the LORD in that great building long ago that another religion would spring up and overtake the church for hundreds of years. And then you explained the Gospel would go out to the ends of the earth. It would even go out to a New World they didn’t even know existed. Then you explained believers from there would return with the same unconquerable message of Jesus in order to share it back in this city–they’d be in disbelief and wonder. Thinking about it now, hopefully they’d say, “take the city and the building, we have Christ, the conquering King, who is returning to set up a city, Church, and temple of God not made with hands, that will never end.”

That’s where our focus and hope must remain. That’s the filter through which we keep the world’s lies at bay, and also through which we also see the world around us and where it’s all headed.
