The Way is the choice of freedom over slavery. The Truth is about seeing reality through the eyes of faith rather than accepting enticing lies. The Life is attained by hoping and trusting in God’s grace — the uncreated gift of his very life — rather than clinging to the merely created biological life which has no power to sustain itself.
Satan tempts Jesus in the reverse order. First, Satan tempts with the idea of mere bread versus the life-giving word of God, which is another term for Jesus himself, who also happens to be the Bread of Life, in addition to the Eternal Word of God made flesh. When Jesus replies that man is not to live on bread alone, but by every word from the mouth of God, he has referred directly to himself in a double sense.
In the second temptation Satan now quotes scripture. Satan is a liar, the Father of Lies, a murderer from the beginning (having brought death into the world in the Garden of Eden). If he’s quoting scripture, you know there’s something wrong. He tells Jesus, by way of that scripture quote, that if he throws himself off of a high rooftop, the angels will catch him before he hits the ground. Like the most enticing of lies, it is based on a truth taken in too narrow of a sense. Jesus brings to light the broader truth that reveals the tempter’s deceit, saying that the greater truth in play is that you do not tempt the Lord your God, which in tempting God the Son, Satan is immediately doing.
In the final temptation, Satan offers all the power and wealth of the world in exchange for Christ kneeling down in worship of the Devil. This is the epitome of the freely chosen loss of freedom — a descent into utter slavery (which as we have said elsewhere, Jesus has said anyone who sins is a slave to sin). The remedy to this temptation is the worship that does not trade in our freedom, but where freedom coincides perfectly with obedience to God, which is another way of saying love.
