Christians can stumble through temptations in unguarded moments due to pride, arrogance, self-confidence, self-sufficiency, laxness or laziness.  When you fall down, turn over on your knees.  Confess, taking full responsibility for your actions.  Be totally honest.  From your knees, cry out to your Lord and Master. From that position you can grasp the hand which will lift you up.  Get up and stay in the race.

“Therefore let him who thinks he stands take heed that he does not fall. No temptation has overtaken you but such as is common to man; and God is faithful, who will not allow you to be tempted beyond what you are able, but with the temptation will provide the way of escape also, so that you will be able to endure it.” 1 Corinthians 10:12-13 (NASB)
