For the grace of God has appeared that offers salvation to all people.  It teaches us to say “No” to ungodliness and worldly passions, and to live self-controlled, upright and godly lives in this present age,  while we wait for the blessed hope—the appearing of the glory of our great God and Savior, Jesus Christ,
(Titus 2:11-13)

Having the Holy Spirit indwelling us gives us the upper hand in the world we live in.  We have a live-in conscience that helps us make better choices.  I'm not saying that I don't sin and lose control from time to time....OK, often...... but I am saying that the Holy Spirit helps me keep on track and also helps me 
recognize when I jump the track.  The world's a tough place but I have  extra insurance, knowledge, and protection given to me by the Holy Spirit.  And you can have it too....by the grace of God!
