I am not tempted to sin, but I am not a baby Christian either.
Jesus was only shown temptation in the desert, so that he could know what humans go through.
Well I get tempted, although now I know what's right and wrong and God does strengthen me to overcome, but I still have to suffer at times to deny myself and say no, but the way I used to live is dead to me now.
We all sin, regardless of what anyone says, even wrong thoughts are sinful, but hopefully those born of God are stronger now that they are blessed with the Spirit, and we can turn from sin as Christ by the Spirit shows us our sins.
But we all sin, if anyone says they don't sin, they are a liar! But once we realise we've sinned, then we are to go to God confess our sins and pray for forgiveness and put it right if we can.
1 John 1
If we say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. If we say that we have not sinned, we make him a liar, and his word is not in us.
As for Christ Jesus, Jesus wasn't only tempted in the desert, he was tempted throughout his ministry
Luke 22:28
Ye are they which have continued with me in my temptations. And I appoint unto you a kingdom, as my Father hath appointed unto me
The apostles were not with him in the desert yet they continued with him in his temptations. So he was tempted when he walked with his apostles preaching the gospel, yet he didn't sin.
Jesus was tempted in all points as we are, thus he would have been tempted in the same way as we are tempted.
Jesus could have sinned, but he didn't and he overcame Satan and the world and brought to us a new and living way to worship the father. In Spirit and in truth. And through Christ, by the power of the Spirit, we can overcome the world too.
