They should tell no one the things they had seen, till the Son of Man had risen from the dead

Mark 9:9
He commanded them that they should tell no one the things they had seen, till the Son of Man had risen from the dead.

On the surface we often think that this only refers to the disciples, that Jesus did not want them to reveal His plans to others. However, this can also apply to ourselves. It can be advice to us that unless we are ready, perhaps we should refrain from telling others about such things as miraculous experience and so on. The telling of the Gospel should not be limited in this sense. In fact, it is often new converts who are usually most excited and want to tell the new faith in Jesus to others. However there are other deeper spiritual matters that God reveals to us, that we can only fully grasp with the maturity in walking with the Spirit, only then perhaps we should council others on those matters.
