"But God proves his love for us in that while we were still sinners Christ died for us. How much more then, since we are now justified by his blood, will we be saved through him from the wrath." (Romans 5: 8 – 9)
Christ's death reconciled us to God. To see the fruits of this reconciliation, we must accept Christ into our hearts through Baptism. This makes us the children of God and the brothers of Jesus Christ. If we remain God's children, our salvation is guaranteed.
