Persistence

Taking one away with the desires of the flesh is easy but strong convictions aren't so easy to stay at something. However dear to you is something, someone but the time comes and normally takes it away from you. You don't want that to happen. You try to stay firm, steady. But there will always be some force working which is powerful enough to drift you away.
This is a normal phenomenon in almost every individual's life. We're vulnerable to breakdown. Sometimes easily and rare times we break later. There are reasons to it and they differ from person to person, depending on their faith in themselves or in something(maybe love, relationship).
But whatever it is, I tell you it is AMAZING when you overpowered the situation.
