I hear what you're saying, but the principle doesn't really make sense to me. What are we to say about those who practice bestiality? Or, any other sin? Must christ experience sin in order to help those who struggle with it?
Yes or no, was Christ tempted in all points like as we are, yet without sin? Christ doesn't have to actually sin to experience the temptation to sin. Christ, being tempted, can now help us overcome the temptation without it getting to the point of sin. In other works, Christ can now be touched with the feelings of our infirmities.
Hebrews 4:
15 For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin.
16 Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need.
