Spend time getting to know him where he is comfortable. If he seems to avoid you at first, spend time just sitting quietly on the floor, not approaching him, not trying to pick him up.
Rabbits are naturally wary, but also naturally curious.
Eventually curiosity will win out and your rabbit will come over to investigate you. Try snuggling close, face to face. When he feels comfortable with you, he may allow you to pick him up. Do not rush this introduction. Remember, a rabbit is an animal of prey, and it may take time for him to gain trust in you.
