The universality of Christ’s redemptive work means that he shed his blood for all persons. For example:Then as one man’s trespass led to condemnation for all men, so one man’s act of righteousness leads to acquittal and life for all men. (Rom. 5:18)
For God has consigned all men to disobedience, that he may have mercy upon all. (Rom. 11:32)
Christ Jesus…gave himself as a ransom for all… (1 Tim. 2:6)
For to this end we toil and strive, because we have our hope set on the living God, who is the Savior of all men, especially of those who believe. (1 Tim 4:10)
Yet, not all will avail themselves of God’s grace:Rom. 14:15 If your brother is being injured by what you eat, you are no longer walking in love. Do not let what you eat cause the ruin of one for whom Christ died. (Rom. 14:15)
And so by your knowledge this weak man is destroyed, the brother for whom Christ died. (1 Cor. 8:11)So while Christ’s redemptive work is for all, the Church does not teach that all must therefore be saved because some will make “shipwreck” of themselves, to borrow another term from Paul.
