"Therefore do not let what you know is good be spoken of as evil. For the kingdom of God is not a matter of eating and drinking, but of righteousness, peace and joy in the Holy Spirit, because anyone who serves Christ in this way is pleasing to God and receives human approval" (Romans 14:16-18, NIV).
Have you ever heard stories of churches that have split over the choice of carpet colors, whether or not to switch from pews to chairs (and then what color), or what kind of music to play or songs to sing? Sounds silly, huh. What about marriage. How many divorces have listed "irreconcilable differences" as the reason for final seperation? Or, friendships and connections that have ended because of this text, that facebook posts, didn't get invited to that event, or any number of instances that often times get blown too far from reason or rationale?
Focusing on what seperates us will keep us from seeing JESUS. If you identify as a believer in Jesus, keep your focus on Him. That doesn't mean you don't have feelings or that you're not hurt when your opinions seem disregarded. But keep in mind that it is Satan who came to bring division and destruction to what God created. He created Adam and Eve, not just for reproduction, but for reflection. What they had together was a reflection of the unity God had with Adam and what was experienced in the Trinitarian relationship of God (Father, Son, Holy Spirit).
It was Jesus who came to HEAL US & to UNITE US. Let Him start it in you. Major on what is non-negotiable, but keep that list to a minimum. Be careful not to allow emotions to morph something that should be minor into something major. Your feelings should be disqualified from making that decision. Use more than just your heart. Use God's heart. Let Him guide you through the feelings and restore the connections that He has purposed for you.
