"Look carefully then how you walk, not as unwise but as wise, making the best use of time, because the days are evil." Don't be foolish. Understand what the will of the Lord is. Don't be drunk with wine, it's debauchery, but be filled with the Spirit.
That's a quick summary of Ephesians 5:15-18. I really wanted to get to verse 19. We are to "address one another in psalms and hymns and spiritual songs, singing and making melody to the Lord with all your heart..." The Word of God should be so abundant in our lives that we can just start gushing it when we talk to each other. Just like the Word of God should fill any worship service through the singing, preaching, reading, and praying; our lives should be fill with the Word of God. It is the only source and authority over our lives. It is the key to understanding the character of God and what he demands from us. It is God's words for us to read and live and know. As Hebrews 4:12 says, "For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart." The word of God will reveal the sin in our lives and direct us in the way God would have us go.
Praise God for His Word.
