Sincerity of our faith

Did you know that God is very concerned about the sincerity of our faith? Probably more than most of us are. Hebrews 10:22 (NIV) let us draw near to God with a sincere heart in full assurance of faith, having our hearts sprinkled to cleanse us from a guilty conscience and having our bodies washed with pure water. We can all look good like good Christians on the outside. I accepted Christ in 1983. And in that time, I learnt a lot of Christianese. You got to know a lot of these if you are going to be a pastor. :) And when it comes to Christian ministry – I think I’ve got quite a lot of brownie points. But you know what? At the end of the day, when I come before Christ, it is about the sincerity of my faith. Sometimes, I forget and God will remind me! What do you think?
