For the grace of God that brings salvation has appeared to all men. It teaches us to say no to ungodliness and worldly passions, and to live self-controlled, upright and Godly lives in this present age. Titus 2:11-12
First of all, memorize this passage.
Dwell on it, drink it in, get into your very soul. Play with it in your mind. Keep it churning and churning and spinning around in your head. Close your eyes and meditate on it. It will be time well spent.
A number of years ago there was a famous anti-drug campaign: just say no. Whether it worked or not is unclear, but let me just say that it was a good starting point (on its own it was doomed to fail without something to replace it). And so it is with us and sin (ungodliness and worldly passions). It’s a start. Is it the be all to end all? Part of the problem is that we put ourselves in situations that are tempting and once we’re down that path, it’s next to impossible to turn back.
What areas of temptation are you susceptible to? Only you can answer that. Scripture does tell us that we can say “no” to ungodliness and worldly passions.
