I lament of my behavior quite often, but today is one of those days I came to myself. I am not esteemed by the Lord for my behavior, but by my faith.
Faith in Christ is the one and only thing you have as a believer that separates you from those outside. It's what God admires and loves about you; it's what pleases Him about you. He doesn't regard you according to your performance, but your faith. Faith is all you have, so be person of impeccable faith. Your behavior and your mood will rise and fall in this life. That is why the promise of eternal life is not granted to you through the currency of good behavior and generosity, but is freely given through placing your trust in Christ.
Mankind has two options with God:
1. Being a law-man
2. Being a faith-man
The law-man lives a life of ceaseless labor and doubt. You could say his good behavior locks him out from the kingdom. He lives only to glorify himself, while the person of faith lives to glorify God in Christ. And more than that...he also receives glory from God. Why? Because he dared to take the risk of escaping hell through something that seems like utter folly to the natural mind: simple trust.
Faith is the only obedience you have that merits anything with God.
