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. Colossians 3:16
Sharing life happens when we worship, pray and open the word of God together, and share what the Holy Spirit is revealing to our hearts through His word. So many times, when you share what God is saying to you, what you are learning from His word, those thoughts will challenge or encourage others too. Sharpening is about sharing with one another what God is saying and doing so that we can all grow in our faith.
