John Calvin on John 14v5:
... whoever obtains Christ is in want of nothing; and, therefore, whoever is not satisfied with Christ alone, strives after something beyond absolute perfection.
14v6:
All believe and acknowledge that the happiness of man lies in God alone: but they
afterwards go wrong in this respect, that, seeking God elsewhere than in Christ, they tear him — so to speak — from his true and solid Dignity.
...
Wherefore all theology, when separated from Christ, is not only vain and confused, but is also mad, deceitful, and spurious.
Matthew Henry on 14v6:
"No man cometh to the Father but by me." Fallen man must come to God as a Judge, but cannot come to him as a Father, otherwise than by Christ as Mediator. We cannot perform the duty of coming to God, by repentance and the acts of worship, without the Spirit and grace of Christ, nor obtain the happiness of coming to God as our Father without his merit and righteousness; he is the high priest of our profession, our advocate.”
"I am the way, the truth and the life" is, God-willing, the glorious text for the evangelistic outreach meeting tomorrow - messages from past weeks are
