There’s a common expression: “It’s not rocket science”. This expression is used to call attention to the fact that a particular topic is not, or does not have to be, complex. The topic is actually a lot more simple than many people might make it out to be.
This is true about topics of a spiritual nature. Jesus said:
“I thank you, O Father, Lord of heaven and earth, that you have hidden these things from the wise and understanding, and revealed them to little children. Yes, Father, for so it was well-pleasing in your sight.” (Luke 10:21)
“Religious” people throughout history have turned spiritual truths into complex systems of theology that the “average” person has no ability to comprehend. In doing so, a separate class of people (referred to as clergy) evolved who were the elite few that could really understand spiritual truths. They were given titles and positions of authority to whom other, less spiritual, people deferred.
Jesus came to teach us that this was not how it works. He basically said, “It’s not rocket science”. Spiritual truths can be understood by anyone who would listen with the simplicity and innocence of a child. Jesus said:
“Allow the little children to come to me! Don’t forbid them, for the Kingdom of God belongs to such as these.” (Mark 10:14)
We must refuse to subjugate ourselves to “spiritual professionals”. They don’t know what they’re talking about. They turn simple truths into complex theologies.
If we can humble ourselves as little children we will find that the words of the Father, brought to us by His son, are simple and easy to understand.
