When we make that initial decision to follow Christ, there should be a change in the way we behave. Christ comes in and there should be less room (or no room) for our old self. And each day after that first, we should continue to be intentional and “die” a little more each day from our previous life and transform more to the life that Christ died for so He can fully indwell in us, without us taking up space.
Lord, I made the decision once to follow You and now I recommit each day to die a little bit more and be different than the way I once was.
