Change? Change to what? We teach Christ, and Him crucified for our sins for 2,000 years now! Or do you mean, change from Judiasm to Christianity 2,000 years ago? To the Jewish children, Paul's doctrine was certainly radical in those days, but not today. Bless the LORD.
Thats the problem! You teach the SAME BASIC THINGS OVER AND OVER AGAIN.
"Therefore let us move beyond the elementary teachings about Christ and be taken forward to maturity, not laying again the foundation of repentance from acts that lead to death,and of faith in God, instruction about cleansing rites, the laying on of hands, the resurrection of the dead, and eternal judgment. And God permitting, we will do so." Hebrews 6:1-3
You teach repentance, tithe, death/ resurrection of Christ and judgement. These are all good but these are the MOST basic teachings and they are quite elementary. These are simply foundational teachings that you are supposed to build upon. But the problem is, most of Christianity HAS NOT progressed and moved forward. This is why the church has gotten away from its true purpose which is manifest the love of Christ to the world. They are still stuck on these same teachings.
It is time to move on to deeper things and stronger meat. The sincere milk of the word is good while we are still babes but it is time to grow up in God.
How about teaching how to manifest Christ to the world through love. How about how to raise the dead, how to heal the brokenhearted, how to give to those in need, what it really means to be in Christ etc??
How about what it means to be a true Christian?? Being a true Christian is not about how many times you go to church, what church you go to, how many bible verses you can quote. Being a true Christian is about how many lives you've helped change, how many people you help and whether or not you constantly seek to make the lives of others better.
Christianity is in need of a reformation and a revival.
