Jesus did not commit Himself to them, because He knew all men

John 2:24-25
But Jesus did not commit Himself to them, because He knew all men, 25 and had no need that anyone should testify of man, for He knew what was in man.

Our Lord Yshua knows us well. So we too should know ourselves enough not to place our full confidence on each other. All humans are fallible, even the best of us. The best solution is to put our trust in Yshua Himself who never fail.
