Isaiah 12:4-5

And in that day you will say, “Give thanks to the Lord, call on His name (in prayer). Make His deed known among the peoples (of the earth); proclaim (to them) that His name is exalted!” Sing praises to the Lord, for He has done excellent and glorious things; let this be known throughout the earth.

When we share with others all that God has done for us, we become His greatest witness. Everyone is searching for help and guidance in a lost world. We are thankful for all that God has done and show through our lives what He wants to do for everyone. When we sing the Praises of God, we give our thanks and draw closer to Him.
