He is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world.
1 John 2:2 (NIV)
Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus. --- Philippians 4:6-7 (NIV)
