“Was it possible for Jesus to sin? Some might contend that such a question is pointless to ask in light of the historical fact that Jesus did not sin (John 8:46; 2 Corinthians 5:21; Hebrews 4:15; 7:26; 1 Peter 2:22; 1 John 3:5). Admittedly, this is not the most pressing of questions we need to consider, but nevertheless, it has value for our understanding of the person of Christ--specifically to what extent He identified with us in our humanity, and the identity of His person.
Seeing that Scripture only affirms the historical fact of Christ's sinlessness, determining whether it was theoretically possible for Him to have sinned cannot be settled by an appeal to Scripture. It must be settled via larger theological categories, considerations, and concerns.”
