God uses His Word and its proclamation to birth and sustains His church. Every believer needs the regular teaching of God's Word.
Psalm 1 Blessed is the man who walks not in the counsel of the wicked, nor stands in the way of sinners, nor sits in the seat of scoffers;  but his delight is in the law of the LORD, and on his law, he meditates day and night.  He is like a tree planted by streams of water that yields its fruit in its season, and its leaf does not wither. In all that he does, he prospers.  The wicked are not so, but are like chaff that the wind drives away.  Therefore the wicked will not stand in the judgment, nor sinners in the congregation of the righteous;  for the LORD knows the way of the righteous, but the way of the wicked will perish. (ESV)
Colossians 3:16–17 Let the word of Christ dwell in you richly, teaching and admonishing one another in all wisdom, singing psalms and hymns and spiritual songs, with thankfulness in your hearts to God.  And whatever you do, in word or deed, do everything in the name of the Lord Jesus, giving thanks to God the Father through him. (ESV)
