I was reading recently in Mark 10:13-14, Christ is out teaching and some bring him their children, the disciples begin to rebuke the people but Christ is "displeased" with what they are doing and then invites the children to him and then teaches a very important principle that I think is very misunderstood, he states "forbid them not: for of such is the kingdom of God." He is teaching that children are pure in heart and are like those that receive the kingdom of God. Some teach that unless children are baptized or christened they will go to Hell. I feel like this verse clarifies that debate.
