Now, how can a sinner be saved? your works got you to where you are. How can you be saved from wickedness by your works, what could you do to wipe out your past, nothing. What can you do to change your heart? Nothing. What can you do to please God? What can you do to satisfy God’s Law? Nothing! So if you are going to be saved it has got to be by Grace; in other words it has Got to Start with God. God must do the saving.
Humanism is the doctrine that man needs no savior outside of himself. Divine theology, the Gospel is that man has no savior except the Lord, God almighty, Father Son and Holy Spirit revealed in the Holy Scriptures. God is the savior of Sinners. So salvation has to start with God. It was, according to Scripture, purchased by God sending his son into the world in the likeness of sinful flesh, taking a real humanity into union with himself so that he could live, he could suffer, he could bleed, he could die in our place. He could pay the price and the ransom for our guilt and reconcile us to God. Having died, he should rise again from the dead to break the power of death and sin and hell and give us a union with himself in a living Christ.
Now, God offers this salvation free of charge, you don’t pay for it, you don’t work for it. It is not by tears of repentance, it is not by church or sacrament; it is by faith in Jesus Christ. Salvation by grace alone, that is it comes from God, freely because he loves us, In Christ alone, because he purchased it by his death on the cross, and it is through faith alone, you receive Christ by faith, not by works, not by effort, but trusting Christ.
When you trust Christ you will find you will never be put to shame, He that beleiveth on Him, has everlasting life” this is what we mean by being saved by grace, through faith.
