Commentaries:
Jamieson, Fausset, and Brown
"If He were to set His heart on man," either to injure him, or to take strict account of his sins. The connection supports rather [UMBREIT], "If He had regard to himself (only), and were to gather unto Himself (Psalms 104:29) man's spirit, etc. (which he sends forth, Psalms 104:30; Ecclesiastes 12:7), all flesh must perish together," etc. (Genesis 3:19). God's loving preservation of His creatures proves He cannot be selfish, and therefore cannot be unjust.
