The New Testament was still in its infancy, so the Thessalonians didn't have the words of the apostles written down like we do - but we still need more than a pen and our own Bible, as important as those personal quiet times are. Something that we lack in our faith is built up when we hear the word of God proclaimed. We are equipped by our pastors and teachers, prepared for service and built up to a more mature faith. Every time we hear a Biblical sermon or sit under a sound teacher, something is supplied for our faith that wasn't there before. Our part is to recognize that our faith needs this impartation of the word, and to regularly put ourselves in a place where it's taught, with a heart attitude to receive it.So faith comes from hearing, and hearing through the word of Christ. (Romans 10:17)So Christ himself gave the apostles, the prophets, the evangelists, the pastors and teachers, to equip his people for works of service, so that the body of Christ may be built up until we all reach unity in the faith and in the knowledge of the Son of God and become mature, attaining to the whole measure of the fullness of Christ. (Ephesians 4:11-13)
Here's the ministry challenge for this passage: If you are not in one of the spiritual roles mentioned in Ephesians 4:11, then thank God for your church leaders who do bear this responsibility. Pray for them to impart the word of God accurately, and for them to have the time to prioritize prayer and Bible study. Recognize that as their primary job. Thank them for it. Pray every day this week that when you come to church next Sunday God will use your pastor's words to supply something lacking in your faith. Let God use him for the purpose He gave him to your church - to build you up and mature you.
If you are in one of these spiritual roles, I'm sure you recognize the profound responsibility that you have to the body of Christ and the vital importance of handling the word of God accurately. However, take some time to recognize the importance of having what is lacking in your own faith supplied as well. Who is your "pastor" or teacher? Take some time this week to receive a word from God that you don't have to research, write, or determine how to communicate to others. He has a word that is just for YOU. It will supply what is lacking in YOUR faith, and it will build you up for the work you are doing in His church this week.
Jesus loves His church. This is one prayer we can be sure He answers - to clear the way for His people to hear His word.
