As a father has compassion on his children, so the LORD has compassion on those who fear him; (Psalm 103:13)
Why does the Lord have compassion on those who fear him? The reason is given in the very next verse which says,
"for he knows how we are formed, he remembers that we are dust. (Psalm 103:14)"
No human being however strong or intelligent can stay alive forever. Only Enoch & Elijah according to the Word of God have been translated to heaven without dying. Scientists may not agree that we are dust, but that is a fact and the curse that Adam was given by God on sinning stated,
"By the sweat of your brow you will eat your food until you return to the ground, since from it you were taken; for dust you are and to dust you will return." (Genesis 3:19)
Shall we then humble ourselves at the Lord's feet and give ourselves wholly to him knowing that it is only because of his compassion that we have breath and are living?
