Prayer of a Civil War Soldier

"A letter attributed to a Civil War soldier expresses God’s prayer priorities and the ultimate desires of the heart shaped by the Holy Spirit: 

'I asked God for strength, that I might achieve.
I was made weak, that I might humbly learn to obey. 

I asked for health, that I might do greater things.
I was given infirmity, that I might do better things. 

I asked for riches, that I might be happy.
I was given poverty, that I might be wise. 

I asked for power, that I might have the praise of men.
I was given weakness, that I might feel the need of God. 

I asked for all things, that I might enjoy life.
I was given life, that I might enjoy all things. 

I got nothing that I asked for, but everything that I hoped for.
Almost despite myself, my unspoken prayers were answered. 

I among all men am most richly blessed.'"
