140. If even the contemplation of sinning is a sin (i.e. "sinning in your heart"; see, for example, Matthew 5:2
and if Jesus was tempted by Satan in the desert (Matthew 4:5-8, Luke 4:5-9), how can you say that Jesus was without sin?
The Bible doesn't say that Jesus thought about sinning; it only says that Satan tempted him. There are three main things that make us sin: the devil, the world, and the flesh. The flesh is the one that is responsible for "sinning in your heart." Because of His divine nature, Jesus did not and could not sin in your heart.
