If you do not seek union with God and want to be holy, you have a ton of things to remember to follow . . . do this, do that, don't do this, don't do that . . . the list is endless. But if you seek and attain union with God, there is not one thing to remember, let alone struggle against. For now the Lord God does all the work for you, in you, and through you; you just keep him company.
