'Walk' in the Bible

Looking at him, Jesus felt a love (high regard, compassion) for him, and He said to him, “You lack one thing: go and sell all your property and give [the money] to the poor, and you will have [abundant] treasure in heaven; and come, follow Me [becoming My disciple, believing and trusting in Me and walking the same path of life that I walk].”

Peter started saying to Him, “Look, we have given up everything and followed You [becoming Your disciples and accepting You as Teacher and Lord].”
