The transfiguration of Jesus is one of the typical facts of the resurrection of the body; not only of the glorious change, but of the renewed life of the body and of the general judgment day.
The life of the individual believer, his personal salvation, and personal Christian graces have their being, bloom and fruitage in prayer.
Every preacher who does not make prayer a mighty factor in his own life and ministry is weak as a factor in God's work and is powerless to project God's cause in this world.
Our praying, to be strong, must be buttressed by holy living. The life of faith perfects the prayer of faith.
