If you believe that God chose some specifically to be damned, wouldn't that be praying against His will?
i often see the criticism levied that if God irrevocably destined for salvation all who are being saved, there is no motivation to evangelize. i find it equally critical that if God is unjust to intervene and coerce a person to believe and be redeemed, then there is contradictory to pray for anyone, because prayer is directly asking God to do exactly those things, superseding the will of the lost.
