When we were young, we looked forward to being adults, so that we can get the same privileges as them, also we can work and make money and get what we dream for.
So much of life is about being “big” enough, to drive a car, to own a house, to vote and to get married. Perhaps we dream some day I can be like someone to be successful and rich.
In New Testament times, children were loved but not highly valued in society until they “became of age” and could contribute to the home and enter the synagogue with adult privileges. Jesus broke the standards of His day by welcoming the poor, the diseased, and even children. Three gospels (Matthew, Mark, and Luke) tell of parents bringing little children to Jesus so that He might lay hands on them and pray for them.
The disciples reproached the adults for what they saw as an inconvenience. At this, Jesus was “indignant” and opened His arms to the little ones. He lifted their value in His kingdom and challenged all to become like children themselves—to embrace their vulnerability and need for Him and to know Him. It’s our childlike need that makes us “big” enough to receive His love.
