Grace doesn't make us overconfident in the sense that we think we can dismiss God and roll down the windows to whatever and we'll be ok. Let anyone who thinks that he stands (that he is too strong to fall) take heed lest he fall. That attitude positions him or her for a fall. We all face the same temptations - nothing new under the sun, but remember this: God is faithful. His answer isn't to roll down the window and let temptation in, His answer is to give us strength to endure the temptation and an eventual way out of that temptation.
