“So then it depends not on human will or exertion, but on God, who has mercy.”
God’s mercy is a side that many non-Christians don’t see. They only see a God who judges. They see the God who commanded the Israelites to completely exterminate all other nations living in Canaan. They see the God who demands perfection. But God is also merciful. He extended forgiveness and an opportunity for us to be with Him, despite not being perfect. What makes it mercy is that He had no obligation or reason to do so, other than love for us. Never forget God’s mercy.
