'Enter into Life' in the Bible

And if thy hand or thy foot causes thee to stumble, cut them off and cast from thee. It is good for thee to enter into life crippled or maimed, than having two hands or two feet to be cast into the eternal fire.

And if thine eye causes thee to stumble, remove it and cast it from thee. It is good for thee to enter into life one-eyed, than having two eyes to be cast into the hell of fire.

And he said to him, Why do thou call me good? There is none good except one, God. But if thou want to enter into life, keep the commandments.
