When you begin a relationship with Jesus, God desires to bring about a metamorphosis in your life. It's just like the amazing process the caterpillar experiences when it becomes a butterfly. The only difference is our change not merely external.
Dear brothers and sisters, I plead with you to give your bodies to God because of all he has done for you. Let them be a living and holy sacrifice, the kind he will find acceptable. This is truly the way to worship him. Don’t copy the behavior and customs of this world, but let God transform you into a new person by changing the way you think. Then you will learn to know God’s will for you, which is good and pleasing and perfect. Romans 12:1, 2 New Living Translation
Giving our bodies to God as a living a holy sacrifice means total dedication. The words we speak, the things we do and even the thoughts we think should bring honor to Him. Considering what Jesus has done for us, it's the least we can do for Him.Consider what your Bible says about your words:
"Don’t use foul or abusive language. Let everything you say be good and helpful, so that your words will be an encouragement to those who hear them." Ephesians 4:29
All of your deeds should be honorable: "...whatever you do or say, do it as a representative of the Lord Jesus." Colossians 3:17
Even our thoughts are important to God: "...we take captive every thought to make it obedient to Christ." 2 Corinthians 10:5
Don't let the world squeeze you into its mold and drag you down to its level of immaturity. God transforms our lives by changing the way we think. That's why it's critical to fill your mind with good things. "Fix your thoughts on what is true, and honorable, and right, and pure, and lovely, and admirable." Philippians 4:8 It's easy to get sucked into watching the popular TV shows and movies, listen to the latest music or read the NY Times bestseller. When you have a relationship with Jesus, He wants you to fill your mind with things that are beneficial. Whatever we think about is what we will eventually act upon.
