Thou hast made known to me the ways of life
That is, thou hast raised me from the dead. When God raised Christ from the dead, he showed him, or made him to know experimentally the way of life, or the way of the resurrection from death to life; and this path of life, or of the resurrection to an immortal and eternal life, was first shown to Christ, who is the first fruits of them that slept, and the first begotten from the dead.
Thou shalt make me full of joy with thy countenance;
or glorious presence, in which is fulness of joy; which Christ, as man, is in, and fully possessed of, being exalted at the right hand of God, and crowned with glory and honour, and has all the joy that was set before him in his sufferings and death.
