Did Christ demonstrate a fear of God?
Yes, Christ feared God the Father. The fear of God involves reverence, respect, and honor. Jesus Christ submitted to God the Father in His incarnation, public ministry and in His death and resurrection. He was an example of giving God the praise and honor that is due to Him. God is worthy of all our praise – on the other hand, if God is not praiseworthy, then He is not God. Here, Kevin Swanson explains that we can learn much from the life of Christ - specifically, how He feared and honored God the Father.
John 12:49 (NKJV) – “For I have not spoken on My own authority; but the Father who sent Me gave Me a command, what I should say and what I should speak.”
Christ himself feared God, feared God the Father. That represented something of his relationship with the Father, which makes a tremendous amount of sense because, again, the fear of God is so essential in our relationships. That fear is respect, it's reverence. It's a due recognition of the value, the importance, the significance, the praiseworthiness of the object that is feared. And If God is not praiseworthy, if God is not to be valued, then God is not God.
This addresses His very Godness from the perspective of our Lord Jesus Christ and from ours as well.
