How do we know that Jesus gave Himself for our sins?

The New Testament provides ample evidence that Jesus gave Himself for our sins, as stated in Galatians 1:4. He is depicted as the Lamb of God, who takes away the sin of the world (John 1:29), and this sacrifice is not only universal in its scope but specific for those whom the Father has given Him (John 6:37). In 1 Peter 1:18-19, it is affirmed that we are redeemed not with perishable things, but with the precious blood of Christ, a lamb without blemish. The significance of His sacrifice highlights that it was not just a historical act but a necessary provision for our salvation, emphasizing His role as the propitiation for our sins (1 John 2:2).
