In the midst of temptation and trial we are often tempted to complain to God, “I’m only human.” We have a high priest, it is true, who can sympathize with our human weakness. He was tempted in every way that we are, yet without sin (Hebrews 4:15). It is also true that God knows our frame, and remembers that we are made of dust (Psalm 103:14). But the other thing, and what I want to highlight right now, is that we are not “only human” in the sense of being left to only fallen human* resources in the fight against sin and Satan and circumstances. Paul tells us in Colossians 1:29 that he strives “with all HIS energy that HE powerfully works within me.” When we are tempted to say “I can’t do this,” the reality is that we CAN, but only through Christ who strengthens us (Philippians 4:13). God wants us to know, not just intellectually, but experientially, “what is the immeasurable greatness of His power toward us who believe, according to the working of His great might that He worked in Christ when He raised Him from the dead” (Eph. 1:19-20, ESV).
*I also want to point out as a side note that it really isn’t quite correct to say “I’m only human” when talking about our tendency to sin. Human does not equal sinful. God’s original intention and design for humanness was to represent Him, to bear His image. The human race has become sinful, but there is nothing human, really, about sin. Sin is the opposite of true humanness, because it’s the undoing of God’s image in us.
