Psalms 39:4-5 (NLT) --- "LORD, remind me how brief my time on earth will be. Remind me that my days are numbered, and that my life is fleeing away. My life is no longer than the width of my hand. An entire lifetime is just a moment to you; human existence is but a breath."
Psalm 118:24 (NASB) --- This is the day the LORD has made; let us rejoice and be glad in it.
James 4:17 (NIV) --- Anyone, then, who knows the good he ought to do and doesn't do it, sins.
