Ephesians 2:4-5: "But because of His great love for us, God, who is rich in mercy, made us alive with Christ even when we were dead in transgressions- it is by grace you have been saved." †
When we were yet sinners, Christ died for us. His mercy and grace stretches so far and vast-- there's no measure to the depths of His forgiveness. His grace is sufficient. His power is made perfect in our weakness. When we're at our weakest, God makes us strong.
