Falling

Therefore let anyone who thinks that he stands take heed lest he fall.

1 Corinthians 10:12

We need to guard our hearts by abiding in Christ, and be on the watch for temptations. As John Owens says below, we may feel confident in our faith, but it’s at that point that we may be the most vulnerable.

“Temptations are abroad in the world, false doctrines, with innumerable other allurements and provocations: we are ready every one to be very confident that we shall not be surprised with them: though all men should fall into these follies yet we would not: surely we shall never go off from our walking with God; it is impossible [that] our hearts should be so sottish.” John Owen - Overcoming Sin and Temptation
