Not all Israel is of Israel. Not everyone in the church is a Christian. One doesn’t inherit eternal life hereditarily or by going to church. Jesus was clear that the church is filled with wheat and chaff (but not to worry about separating the two here on Earth—for fear of ripping out wheat as well as chaff). How sobering it is to think that not everyone who calls Jesus “Lord, Lord” will enter the Kingdom. Imagine going to church every Sunday and saying prayers every night, then on that final day having Jesus say to you, “I never knew you.”
