There are amazing changes in nature such as a tadpole into a frog, a caterpillar into a butterfly. We are told a leopard cannot change his spots as an indicator of impossible transformations. But we are assured that God can change us and our circumstances. Let us remember that God wants good for us and can execute seemingly impossible changes in our life. 2 Corinthians 5:17. "...look, new things have come!". Isaiah 43:19 "See, I am doing a new thing. See it spring up! I am making a way in the wilderness and streams in the wasteland".
