Why are we so eager to pray against suffering?

Philippians 3:3-11

"For we are the circumcision, who worship by the Spirit of God and glory in Christ Jesus and put no confidence in the flesh — though I myself have reason for confidence in the flesh also. If anyone else thinks he has reason for confidence in the flesh, I have more: circumcised on the eighth day, of the people of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; as to the law, a Pharisee; as to zeal, a persecutor of the church; as to righteousness under the law, blameless. But whatever gain I had, I counted as loss for the sake of Christ. Indeed, I count everything as loss because of the surpassing worth of knowing Christ Jesus my Lord. For his sake I have suffered the loss of all things and count them as rubbish, in order that I may gain Christ and be found in him, not having a righteousness of my own that comes from the law, but that which comes through faith in Christ, the righteousness from God that depends on faith that I may know him and the power of his resurrection, and may share his sufferings, becoming like him in his death, that by any means possible I may attain the resurrection from the dead."

Many other versions phrase Philippians 3:10 along the lines of "the fellowship of sharing in His sufferings."

If we find sweet fellowship with our Lord in suffering, why are we so eager to pray against suffering? Are we not essentially praying against fellowship with Him?
