I remember when our children were small, and Marlys and I would set them in a high chair and feed them. OK, Marlys more than me.
If they did not want to eat, you could put all the food in their mouth you wanted, but they would spit it out. Also, if we tried to feed them something they did not want, they would spit it out.
Now, was there any nutritional value to them for what they spit out?
Some things that they would not eat then, they will eat and enjoy today.
At times, we attempt to force feed the lost with the gospel and we do not understand why they spit it out. You will never get anywhere with someone by attempting to shove the gospel down their throat. Why? The door is not open, and only God can open the door.
