Jesus had hundreds of followers, but only 12 apostles. To the crowds, He often spoke in parables; to His chosen few, He spoke more plainly and explained the parables. Let others prove their trustworthiness before you reveal much about yourself. Even then, be cautious. Always remember the deceitfulness of the human heart (including your own).
I’ve seen too many relationships sour because people shared too much about themselves or simply became overly friendly. People tend to be polite and respectful with people whom they don’t know well. That can quickly change as they become more familiar. Those who do best in human relations tend to be superficially friendly with everyone but intimate with only a carefully chosen few.
Another reason for caution is that, in general, people are not good at keeping confidences. Bad news travels faster than good news. Most people love to gossip, so don’t become a victim.
If you “wear your heart on your sleeve” too readily, you will usually find that people won’t understand, won’t care or will treat you with contempt. You’ll also find that your thoughts and feelings will seem to lose some of their value. But, if you are careful to only share them at the right time and with the right people, they can deepen relationships and help others.
Jesus said, “Do not give dogs what is holy, and do not throw your pearls before pigs. If you do, they may trample them under their feet, and then turn and tear you to pieces” (Matthew 7:6). This is a perfect analogy of what usually happens when you share deep wisdom, truths or insights with the average person.
Of course, if you are too guarded, it will be hard to get close to anyone. There are many good-natured, truly kind people in this world. Try to be this way yourself and you will attract them.
Consider yourself blessed if you’ve found one or two people that you can trust enough to share intimacies. Above all, communicate your deepest thoughts to God and trust only Him completely. He will give you the wisdom that you need to develop the best human relations.
