This is what Christianity is all about
You must ask for God’s help. Even when you have done so, it may seem to you for a long time that no help, or less help than you need, is being given. Never mind. After each failure, ask forgiveness, pick yourself up and try again. Very often what God first helps us towards is not the virtue itself but just this power of always trying again. For however important chastity or courage, or truthfulness, or any other virtue may be, this process trains us in habits of the soul which are more important still. It cures our illusions about ourselves and teaches us to depend on God. We learn, on the one hand, that we cannot trust ourselves even in our best moments and, on the other hand, that we need not despair even in our worst, for our failures are forgiven. The only fatal thing is to sit down content with anything less than perfection.
From: Mere Christianity by C.S. Lewis Ch.8 Is Christianity hard or easy?
God gives us a new nature but we must develop the character to go with the new nature. We must work out our salvation with fear and trembling. This is how God shares His glory with us. He lets us get up off the ground after we’ve fallen. He gives us the strength and instruction to get up but He expects us to do it. Remember Lazarus in the grave. Jesus could have walked in and carried Lazarus out in his arms, unwrapped the burial garment and presented him alive and standing. But He simply told him “Get up”. Lazarus walked out into glory on his own two feet in obedience to Jesus. The man with the withered hand, the lame man at the well, the man on the stretcher lowered into the room by his friends; to all He said, “Get up or stretch forth or arise. Stop waiting for him to physically appear and lift you up. Listen to his voice and obey it. If we don’t have these habits of the soul, we cannot develop the character God longs to see in us .
Just Get Up.
