When the pilot of a giant airliner is speeding down the runway, there is a certain point where he cannot decide to remain on the ground. When he crosses that line, he is committed to the air, or the plane crashes disastrously. The pilot cannot change his mind when the plane is two-thirds of the way down the runway.
Many Christians have never left the ground spiritually. They have been sitting there for years & years gunning their engines.
Heb 5:13 (GW): “All those who live on milk lack the experience to talk about what is right. They are still babies.”
“Babies by nature are completely selfish. They think only of themselves and their own needs. They are incapable of giving; they can only receive. That is immature thinking. Unfortunately, many people never grow beyond that kind of thinking.” - Rick Warren.
