“Verily I say unto you, Except you be converted and become as little children, ye shall not enter into the kingdom of heaven.” (Matt. 18:3)
I was raised a Methodist but sometimes visited with my friends the Roman Catholic Church nearby; I accompanied my cousins to the Anglican (Episcopal) Church and with some distant relatives I visited a Pentecostal Church. The pleasure of these attendances was being with friends, cousins etc. I don’t think we paid much attention to what the priest, reverend, pastor or minister was saying as much as fellowshipping with each other. A little pinch here and there from one of the grownups to stop us from chatting or fidgeting kept us in line.
As an adult, imagine my dismay after a long absence from home, to discover many persons displaying contempt and disdain for others who belong to a denomination other than theirs and actually condemning their belief system, even though they are worshipping the same God. We lose the innocence of childhood as we grow into adulthood, becoming biased and our minds polluted with the ideas of the world. “For all have sinned and come short of the glory of God.” (Rom. 3:23), so there is no reason to feel that your membership in one Church gives you easier acceptance into the Kingdom of God over another.
Jesus is the Head of the Church and if we follow Him, we must follow Him in spirit and in truth.
