We either pass or we fail. Toward the end of his life, Peter passed the test that he had once failed, and he gave his life in martyrdom during the persecutions under Nero. Temptation is actually very helpful to us as a way of showing us if there are areas in our lives that are in need of improvement. If we yield to temptation, it is God's way of showing us, through these circumstances, that we have certain weaknesses that need to be addressed. But it is far better to ask God, beforehand, to help us not to fall prey to temptation, since there are always negative consequences when we yield to the tempter, who is out to destroy us.
Temptation is often very subtle.
The tempter is a deceiver, and he will do all that he can to fool us and coax us into yielding to his enticements. He will use very clever arguments in order to convince you, if he can, that your situation is unique, or that circumstances warrant disobedience to what would ordinarily be God's command. What we must remember is that it is never in our best interest to listen to these arguments, however convincing they may seem. You can be sure that the devil does not have your interests at heart when he introduces a temptation to you. The only problem is that God, who knows everything, is not only observing your every action, but He is observing your very thoughts and motivations.
