Apparently some churches are hesitant to preach the true grace that God gives us. That He loves us completely, no matter how much we mess up would possibly urge us to not really care about holiness. Having this amazing grace in our head and hearts might keep us away from studying the bible on our own, or staying away from sin, or not really go to church since we don't really need it.
Others think Christianity is a bunch of rules. They think it is all about keeping us from happiness. Do's and don'ts; keeping us from freedom. A road too narrow to follow.
John Eldredge blends these two thoughts in a great quote:
"It's not that God doesn't want us to be happy. He does. It's just that He know that until we are holy, we cannot really be happy."
God made us. He made us to glorify Him. God's ways are way higher than I could ever imagine, but I do know that I am way more drawn to holy, happy people, than grumpy, ones. He alone can fill us with true joy when we make lots and lots of room for Him by getting rid of the stuff that doesn't really matter...
Have a wonderful Sunday living in His Amazing Grace, pursuing holiness and being filled with happiness.
