Luke 18:28 Meaning

26And they that heard it said, Who then can be saved?

27And he said, The things which are impossible with men are possible with God.

28Then Peter said, Lo, we have left all, and followed thee.

29And he said unto them, Verily I say unto you, There is no man that hath left house, or parents, or brethren, or wife, or children, for the kingdom of God's sake,

30Who shall not receive manifold more in this present time, and in the world to come life everlasting.
