1 Peter 5:6-9a
This is a subject I have recently given quite a lot of thought to. I believe that while we, as Christians, are in a world full of the devil's schemes and traps, we need to be careful, watchful, and "vigilant" about how we live our lives. Are we getting into areas that our Lord would rather we stayed away from? Are things of this life subtly stealing our hearts? Is the devil trying to get in and make you think that you're okay even if you harbor things in your life that displease your Savior?
I believe that walking through this life as a Christian is literally like walking through a mine field... If we aren't really, really, really careful about our actions and the things we allow in life, the devil might get victory. If he does, there will be a detrimental explosion in your faith... possibly a fatal to your spiritual life. We need to be very alert!
Spending time in God's Word will show you very clearly the things you need to do, and the things you should not do. This is God's designed way for us to obtain sensitivity!
Being a Christian means giving up a lot... our comfort, our cravings, our sin. It's radical!!!! It might be a little stressful sometimes trying to live up to the standards set forth in the bible... but isn't that what grace is all about? First, grace saves you from your sin. Then it empowers you to live an upright, watchful life. In Christ, and because of His grace, we can do ANYTHING! (Philippians 4:13) Isn't it invigorating to think of it that way?
Besides, if giving up certain things in this life means gaining eternal bliss in the presence of our loving Creator and Sustainer forever (FAR greater importance in comparison) don't you think that the little bit of suffering would be worth it? (Matthew 16:26)
The Lord will give us a supernatural sensitivity and awareness of His desires if you ask for it!
