The Lord will never send us away, but it are our sins which separate us from Him. Nothing and nobody can take us out of His Hand, but we can walk out of His Hand if we wanted to. And many do, because they do not want to obey, they rather follow their own desires. Brethren, if a man is overtaken in any trespass, you who are spiritual restore such a one in a spirit of gentleness, considering yourself lest you also be tempted. For he who sows to his flesh will of the flesh reap corruption, but he who sows to the Spirit will of the Spirit reap everlasting life.
Corruption clearly means here eternal death.
But everyman is tempted, when he is drawn of his own lust, and enticed. Full-grown sin speaks of sin not confessed, of living in sin, which will bring forth eternal death. Let us therefore be diligent to enter that rest, lest anyone fall according to the same example of disobedience. Dearly beloved, I beg you as sojourners and pilgrims, abstain from fleshly lusts which wars against the soul. You therefore, beloved, since you know this beforehand, beware lest you also fall from your own steadfastness, being led away with the error of the wicked.
