You CAN follow Jesus successfully!  I used to feel constantly defeated in my walk with the Lord.  But following Jesus is not about perfection; it’s about persistence.  The phrase “practice makes perfect” is incorrect.  Really, it’s “practice makes progress”.  The successful Christian life is not about maintaining sinless perfection all the time.  It is about a faithful life direction, pointing toward God, journeying forward, making steady, daily progress with Him.
