"Let not sin therefore reign in your mortal body, to make you obey its passions. Do not present your members to sin as instruments for unrighteousness, but present yourselves to God as those who have been brought from death to life, and your members to God as instruments for righteousness. For sin will have no dominion over you, since you are not under law but under grace". Romans 6:12-14
"Beloved, I urge you as sojourners and exiles to abstain from the passions of the flesh, which wage war against your soul". 1 Peter 2:11
"He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him." 1 John 2:4
The phrase "Know Jesus...know peace. No Jesus...no peace" isn't a cliche: it's a living, breathing reality that's a thriving part of the daily Christian experience. If we say we know Him, we must obey Him!
