I don't expect our kids to just stand up and walk without going through a process first. And I don't scold them when they fall. I cheer them on at every single little step and encourage them to keep trying until they get it right. So it is with my Heavenly Father towards me.
Be confident in His love. Try. Make mistakes. Fail. Learn and put it into practice. But keep coming back to Him until you get it right. He who promised is faithful. Faithful to complete the good work He started in you. The emphasis is on Him anyways, not you. His goodness. His faithfulness. His ability to transform. He is the Potter, I am His clay. So get your eyes off yourself and fix them on Jesus, the Author and Perfecter of your faith. Set your mind on things above and run as one aiming to win the prize.
