Is it against the Lord Christ’s divinity that He prayed and got tired sometimes? How can we interpret His praying, His fatigue and similar things?
Those addressing these questions concentrate on Christ’s divinity and forget His humanity!
He is not only God, but He also took on Him a human nature like ours; a complete human nature. Hence it is written that He shared with us everything except sin (Heb 2:17) and unless He had taken our nature, He would not have been able to satisfy the divine justice on our behalf.
He prayed as Man not as God.
He presented to us the ideal Man. If He had not prayed He would not have been an example, so He prayed.
With His prayer He taught us to pray and how to pray.
He gave us a practical idea about the importance and the value of prayers in our life. In some of His prayers, as in Gethsemane, He even taught us how to struggle in prayers Luke 22:44).
If Christ had not prayed, this would have been an accusation against Him.
The scribes and Pharisees would have considered Him far from spirituality and would have excused not to follow Him saying that He was not attached to God!
With the same human nature He felt tired, hungry and suffering.
If He had not felt tired, hungry, thirsty or suffering, if He had not slept, it would not have been possible to say that He is the Son of Man and that He took what was ours, took the same nature sentenced to death so that He might in it die on our behalf and redeem man.
As God He was not tired because the Godhead is beyond fatigue.
It was the human nature which united with His Godhead and were not separated for one moment or a twinkling of an eye that felt tired because it accepts fatigue. The Lord Christ, so that His incarnation be an established fact able to carry out redemption, did not permit His divinity to prevent His humanity from being tired.
He did all this to pay off for our sins and atone for the sins of the people (Heb 2:1 7). We thank Him for bearing fatigue and pain for us.
With His fatigue He sanctified fatigue and every one is now rewarded according to his labor (1 Cor 3:8).
