In my opinion, that's what is wrong with our "today" churches. People are preaching personal convictions instead of the gospel of Jesus Christ. These debates will continue to go on forever, until WE (the church) realize that WE all have different approaches to Salvation. We all have to sincerely seek God for ourselves, and when we do...HE will guide us into all that is true for our lives.
Christ changes the way we view the world around us. Before salvation, all we seen was ourselves...And Now that we have been changed, it's all about him. Our motives are different. Yes, we live in the world, but we are not of the world. And if we let our light shine among men, they will come to glorify the Father,.....not whether we wear earrings or not. Salvation is bigger than earrings/women speaking in church/ and our denominations. Hopefully when we realize that, we will become more united as a body.
Be Blessed.
