I was going to say The Rich Young Ruler, but then I realized that the Rich Young Ruler came to Jesus and asked to be a follower. After setting forth a series of preliminary criteria which would be expected of a true follower, it seems that he turned Jesus down.
Perhaps someone else can give a better example.
And the LORD said unto him, Who hath made man's mouth? or who maketh the dumb, or deaf, or the seeing, or the blind? have not I the LORD? Now therefore go, and I will be with thy mouth, and teach thee what thou shalt say.
And he said, O my Lord, send, I pray thee, by the hand [of him whom] thou wilt send.
And the anger of the LORD was kindled against Moses, and he said, [Is] not Aaron the Levite thy brother? I know that he can speak well. And also, behold, he cometh forth to meet thee: and when he seeth thee, he will be glad in his heart.
And thou shalt speak unto him, and put words in his mouth: and I will be with thy mouth, and with his mouth, and will teach you what ye shall do. And he shall be thy spokesman unto the people: and he shall be, [even] he shall be to thee instead of a mouth, and thou shalt be to him instead of God. Exodus 4:10-16
19 You know the commandments: 'Do not murder, do not commit adultery, do not steal, do not give false testimony, do not defraud, honor your father and mother.' " 20 "Teacher," he declared, "all these I have kept since I was a boy." 21 Jesus looked at him and loved him. "One thing you lack," he said. "Go, sell everything you have and give to the poor, and you will have treasure in heaven. Then come, follow me." 22 At this the man's face fell. He went away sad, because he had great wealth. 23 Jesus looked around and said to his disciples, "How hard it is for the rich to enter the kingdom of God!"
