It’s unfortunate, but if you have to deal with people, “Christian” or non-Christian, you will not have a peaceful life. Though Jesus left us His peace, it’s a different kind of peace. God’s kind of peace is knowing that when we leave this earth, we will be with Him. No longer must we worry about the ever after. However, we must live our lives, and in doing so, we will encounter people who do not have the same mindset as we do, and who do not have their hearts set toward Jesus. I get frustrated when I’m dealing with people who say that they are Christian and they do not listen to the Holy Spirit or follow the tenets of God. Unbelievers call them hypocritical, and so do I! I get angry because they have identified themselves as believers, yet follow a worldly mannerism. We must remember that they will have to deal with the consequences of their actions, not with us, but with God. Keep your heart turned toward Jesus, and all of the unrighteousness will be burnt up in the fire.
"Peace I leave with you; my peace I give to you. Not as the world gives do I give to you. Let not your hearts be troubled, neither let them be afraid." John 14:27
"I have said these things to you, that in me you may have peace. In the world you will have tribulation. But take heart; I have overcome the world.”" John 16:33
