"Worship the Lord with your life and praise Him with your mouth. A heart surrendered to the Lord and filled with the Holy Spirit becomes like a fountain, pouring out praise."
Those are the words I heard the Lord speak to my heart one morning. God's word clearly tells us that our lives should be our living sacrifice to Him (Romans 12:1). He has shown us incredible love, grace, and mercy, and our response should be to offer Him our lives--not just part of them, but all of them--as a sacrifice of praise. By doing so, we are presenting our worship to God, worship that is not just true and proper but holy and pleasing to Him. We are being obedient to His word. Our hearts should be filled with worship. When they are, our mouths cannot help but speak (or sing!) His praise.
As I thought about this, I was reminded of the story of Zechariah in the first chapter of Luke's gospel. Zechariah was told by the angel Gabriel that his wife, Elizabeth, would bear a son, whom he was to name John. Because Elizabeth, like Zechariah, was advanced in age, Zechariah doubted what Gabriel told him. As a result, his mouth was shut up and he was unable to speak. When Elizabeth did give birth, in obedience to the Lord, Zechariah confirmed that the child's name would be John. Immediately, his voice was restored by God. And what was the first thing he did when his voice was restored? He opened his mouth in praise to God. His heart was so full of worship that it just bubbled up from his mouth in the form of praise.
Lord, in obedience to You, I give my life to You as a sacrifice because of Your great love and mercy. May that sacrifice be pleasing in Your sight. Let my heart be so full of love, fear, and awe of you that praise will always be on my lips. In Jesus' name. Amen!
