How do I truly know my sins are forgiven today?

The apostle Paul proclaims, “If Christ is not risen, your faith is futile; you are still in your sins! . . . But now Christ is risen from the dead, and has become the firstfruits of those who have fallen asleep. For since by man came death, by Man also came the resurrection of the dead. For as in Adam all die, even so in Christ all shall be made alive” (1 Cor. 15:17, 20–22).

Now, is Christ risen? Yes, absolutely! And according to the Bible, because He is risen, you are no longer in your sins. Jesus’ resurrection is the living proof that all your sins have been completely and totally forgiven. You cannot preach grace without preaching the resurrected Christ. We are saved by grace through our faith in our Lord Jesus Christ:

But God, who is rich in mercy, because of His great love with which He loved us, even when we were dead in trespasses, made us alive together with Christ (by grace you have been saved), and raised us up together, and made us sit together in the heavenly places in Christ Jesus, that in the ages to come He might show the exceeding riches of His grace in His kindness toward us in Christ Jesus. For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast.
—Ephesians 2:4–9

Our forgiveness is not contingent upon us and what we have or have not done, so no one can boast that they earned their forgiveness through their own efforts. Through faith in Jesus’ finished work at the cross, we have received the gift of salvation. Salvation is a gift. When something is a gift, it means that you cannot work for it, earn it, or merit it. A gift is lavished upon the recipient by the giver, and Jesus gave of His own life to ransom yours.
