Psalm 22 is generally recognized as referring to the suffering of Jesus, in the events prior to his death and his death itself.
Verses 14-18 in literal and metaphorical terms, graphically describe His suffering, painting a picture of someone brought to state of total weakness.
In that state of weakness, surrounded by strong foes, Jesus cried out to God (v.19-21) and his prayer was heard ( v.21). He was saved from his enemies, Satan, principalities and powers of darkness and his persecutors, when he was raised from the dead. This was prophesied in Psalm 16:10, words referring to Jesus…
10 because you will not abandon me to the realm of the dead,
nor will you let your faithful one see decay.
In his totally weakened state, Christ called out to God, was raised from the dead and it bore great fruit. Verse 22 says…
22 I will declare Your name to My brethren;
In the midst of the assembly I will praise You.
Through his suffering and weakness this was the fruit Christ desired, that he would have brethren, spiritual brothers and sisters with the same Father and the same God as Himself. Hebrews 12 : 2 explains this psalm, why Jesus suffered as he did…..it says…
2 looking unto Jesus, the author and finisher of our faith, who for the joy that was set before Him endured the cross, despising the shame, and has sat down at the right hand of the throne of God.
Jesus for the joy set before him endured the cross, and that joy is described in verse 22 of the psalm, brethren, spiritual brothers and sisters, the church. It was the joy of the birth of the church, that carried Jesus through the cross, it’s great suffering, shame and weakness.
It’s a reminder to us that all works of God are born out of weakness. Our weakness, breathed into by God’s strength. As Paul said in 2 Corinthians 12:10
10…For when I am weak, then I am strong.
….in other words when I am humanly useless, as Jesus was when he died, then I am in fact most fruitful, as Jesus was, when God’s power worked through Him in His resurrection, birthing and bearing the fruit of the church.
Like Jesus, we are divinely most fruitful when humanly useless.
