Life has always been gift and grace. God's grace is even bigger than we thought. John 21 demonstrates this truth to us through His love for Peter after his denial of Jesus as well as through His service to the disciples.
Who is going to sit on the throne? Pharaoh grapples for authority by refusing to release the Israelites, but ultimately it is God who sovereignly hardens Pharaoh's heart that He might get glory.
John 17 gives us the privilege of witnessing an intimate conversation between God the Son and God the Father. Jesus prays not only for His disciples then but for us as well.
We are saved and become Christians by believing in the atoning death and resurrection of Jesus. However, in order to grow and become mature as Christians we must abide in Him.
