To encourage people to spend time with the Lord; listening to His voice, so that when temptation comes, they recognise the voice of the evil one and don't act on it.
To encourage people to take time to be with Jesus; listening to Him and talking with Him and ignoring the distractions that seek to draw them away from Him.
To teach people that when Jesus was transfigured on the mountain and the disciples saw His glory; they saw who Jesus truly is. We can catch a glimpse of Jesus' glory as we spend time alone with Him and time with other christians, but one day we will see His glory in full.
