But whoever disobeys (is unbelieving toward, refuses to trust in, disregards, is not subject to) the Son will never see (experience) life, but [instead] the wrath of God abides on him. [God’s displeasure remains on him; His indignation hangs over him continually.] (Amplified Version) He who believes in the Son has everlasting life; and he who does not believe the Son shall not see life, but the wrath of God abides on him. (New King James Version)

I fast twice a week and give a tenth of all I get.' But the tax collector stood at a distance. He would not even look up to heaven, but beat his breast and said, 'God, have mercy on me, a sinner.' I tell you that this man, rather than the other, went home justified before God.

Galatians 3:1-3; Galatians 3:9-14; Galatians 3:21-25: O foolish Galatians, who hath bewitched you, that ye should not obey the truth, before whose eyes Jesus Christ hath been evidently set forth, crucified among you? This only would I learn of you, Receive ye the Spirit by the works of the law, or by hearing of faith? Are you so foolish? having begun in the Spirit, are ye now made perfect by the flesh? ... So then they which be of faith are blessed with faithful Abraham. For as many as are of the works of the law are under the curse: for it is written, Cursed is every one that continueth not in all things which are written in the book of the law to do them. But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith. And the law is not of faith: but, The man that doeth them shall live in them. Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth on a tree. That the blessing of Abraham might come on the Gentiles through Jesus Christ; so that we might receive the promise of the Spirit through faith.... Is the law then against the promises of God? God forbid: for if there had been a law given which could have given life, verily righteousness should have been by the law. But the Scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe. But before faith came, we were kept under the law, shut up unto the faith which should afterwards be revealed. Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith. But after that faith is come, we are no longer under a schoolmaster.
