The first man, Adam, was challenged to remain sinless in a sinless world. Christ, on the other hand, was challenged to remain sinless in a sin-ridden world. The Son of Heaven was tempted but never failed, struck but never struck down. He succeeded where Adam failed.
Here it is in a nutshell in Romans 5:18 (MSG): “Just as one person did it wrong and got us in all this trouble with sin and death, another person did it right and got us out of it.”
Listen, you and I are no match for Satan. Jesus knows this. So he put on our flesh. He was tempted in every way, just as we are, yet without sin. He was victorious for us. Trust his work. Trust his Word. Hang in there.
