God IS Mercy, Mercy is God
God is Mercy. Everything He does for us, all the good in our life, our existence itself, is in itself Mercy. He doesn't have to do anything for us but He does EVERYthing for us out of HIs Mercy, out of His Love. Given that He gives us so much out of His Mercy, how much more incredible is His Mercy to us when we return to Him after straying from Him, ignoring Him, or even denying Him?
