Contrary to popular belief, love will actually open your eyes.
Church can be (kind of) like a spiritual minefield. One little word out of place, one jot or tittle askew and someone is likely to pack up their toys and go play somewhere else. Hold on a second, would ya?
Before you can deal with the issue of doctrinal distinctions and differences, we need to make sure that we believe and know that God loves us.
How much do you believe? To a secular humanist, it's likely that they don't believe (really believe) in God, or angels, or anything spiritual one iota. But I'm addressing this question to the Christian.
The fact that we know that God is real and that Jesus died for our sins and rose from the dead and gave us the Holy Spirit is a given if you're a Christian. But the fact that He really loves us is something that—in my opinion, to a certain degree, greater or lesser—everyone is blind to. It's going to take all of eternity to see and realize the fullness of God's love for us. So what about right now? How much does God's love color your day? Your actions? Your thoughts and perceptions? God IS love (see 1 John 4:8). Yet when I think about Him sitting on His throne in Heaven, I don't usually see Him as doing anything. It doesn't mean He's not doing something, but around and within everything He does is His tender, fervent, white-hot love for us (and kindness, and respect. We're His creations for God's sake). I'm blind and only going through the motions if I don't recognize this. The whole basis for God's interaction with me is love (see John 3:16).
"The Lord hath appeared of old unto me, saying, Yea, I have loved thee with an everlasting love: therefore with lovingkindness have I drawn thee." (Jeremiah 31:3)
Here's what I'm getting at: if we're not reflecting the love of God that we ourselves see and live back to our brothers and sisters in Jesus, then we're blind and we'll eventually end up dividing (see Hebrews 12:15). God's love is the glue that holds us together. And if the world can't see us overcome the nonsensical, nonessential divisions we've created (I'm not saying your feelings aren't worth anything), then it's not going to want to have anything to do with church or God (see John 12:32) or us.
Everyone's blind to something. The trouble with blindness is that you don't know you're blind. Someone has to tell us, to show us. Please, Holy Spirit. Show us. Thank-you.
"By this shall all men know that ye are my disciples, if ye have love one to another." (John 13:35)
