God changes our lives, not in a flash, but little by little. He uses this incremental approach so we will learn to trust Him. God refines us as we are ready for it. Most the time, we couldn’t handle all He wants for us all at once. More than anything, He wants us to see Him in the story of our lives. If everything became perfect for us in an instant, we would be tempted to take all the credit! So be patient and remember God is working on changing us, little by little.
