How do we know that Jesus Christ is our Savior?

The central truth of salvation is that Christ, the God-man, came into the world to redeem those who were under the law. As stated in Galatians 4:4-5, He was born a woman, made under the law, to redeem those under the law. He succeeded in His mission by living a perfect life, fulfilling the righteousness required by God. Our hope rests in the accomplished works of Jesus, who abolished death and brought life and immortality to light through the gospel, as seen in 2 Timothy 1:10. Thus, believing in Him assures us of our salvation.
