Because Christians must always put others in front of self... in corporal acts of kindness and ethereal acts of prayer ... i dont believe it makes a difference can never be true. Our prayers are meant for the "others" of the world who are all in need of God's help and mercy. Our fervent prayers for them will never go unanswered, will never leave you feeling frustrated, lonely or forced in to action.i wish my prayer life was more like that....i find i dont pray because i find it frustrating....i like to hear someone talk back....and to feel like im not the only one in the room...i know what you mean bout not wanting it to feel forced..... and praying feels forced for me....but i think the real problem is this... i dont believe it makes a difference.
Any prayer for self can be helpful for that moment, but life usually does not end at that moment... what is good today for you in your eyes may not be so tomorrow. We cannot know this, as we only have the grace from God for the present, but God does... and to save us from a greater pain, He does not hear our prayer. Only those who have a faith that is weak or dying fear "not being heard" by God. They do not take in the future possibilities of the " I want" prayers as possibly not the best thing for themselves, but prayer is not meant for themselves, as God already knows what you need, to Him. IMO, the important thing is us showing His love to others in corporal and ethereal works available to us while here on earth.
And prayer is the most intimate of all conversations with God for others or ourselves. Whether we know it makes a difference or not.
