Mark 9: Jesus is revealed to three disciples.

We read:

2-4 ... Jesus took Peter, James, and John and led them up a high mountain. His appearance changed from the inside out, right before their eyes. His clothes shimmered, glistening white, whiter than any bleach could make them. Elijah, along with Moses, came into view, in deep conversation with Jesus.

When the disciples saw Jesus transfigured, every problem on earth should become very small before Jesus' glory.

7 Just then a light-radiant cloud enveloped them, and from deep in the cloud, a voice: “This is my Son, marked by my love. Listen to him.”

The Father talked to the disciples - "listen to Jesus, he is my son, I am glad with him".
In a way, the Father talks to me like that. The Father cares about me. He wants me to listen to Jesus because he wants to extend his love to me through Jesus.
