For us as Christians, no matter what our current circumstances may be, it will always be true that the Lord has dealt bountifully with us. Therefore, we should sing unto the Lord as long as we live, just as the Psalmist says that he would do:
Psalm 13:6 I will sing unto the LORD, because he hath dealt bountifully with me.
Psalm 104:33 I will sing unto the LORD as long as I live: I will sing praise to my God while I have my being.
Psalm 146:2 While I live will I praise the LORD: I will sing praises unto my God while I have any being.
Let us sing to the Lord as long as we live!
