Maintaining your relationship with Jesus is like going to the gym. You don't grow by doing something once. You grow by doing something daily. You maintain fitness with consistency. If you miss a day, you won't lose all your muscles. But if you let the drift mess up your momentum, you'll wonder how you ever got so out of shape.
So today, where are you? How can you make one tweak towards following Christ? Grand, heartfelt repentance is great, but after that there will still be a lifetime of daily decisions. These are what we must master.
