God sees potential in God’s creation in a frame of reference often beyond our ability to grasp. God believes in God’s people as a long term investment - it takes a lifetime of hearing about the goodness of grace before it really sticks.
But God keeps saving anyway. Even when things in the present scream the contrary, God keeps pouring out the Holy Spirit on a bunch of investments that no one in their right mind would put their money on. God saves because that’s who God is.
