How do we know that salvation is grounded in Christ?

In 1 John 4, the text highlights that no one can have a saving relationship with God apart from faith in Jesus Christ, who is the Son of God. The Gospel teaches that Jesus' death and resurrection are the basis for our salvation, as He bore our sins and provided the righteousness necessary to stand before God. Philippians 3 emphasizes that our righteousness comes not from the law but through faith in Christ. Therefore, our hope and assurance of salvation rest solely in Christ's completed work, ensuring that we are acceptable to God.
