Many Christians believe their God (Yahweh) has a perfect
plan for their life and that everything happens according to his divine plan.
However, many Christians also believe in the power of prayer. I don’t think
many Christians have given much thought to the compatibility of these two
concepts. They also haven’t given much thought to God having a plan and
freewill - but that’s a different discussion.
Let’s assume it’s true that a God exists who has a divine
plan for our lives. If this is true, why are believers praying to this God
asking him to intervene in some way? If God has a plan, aren't those who pray
just believers who don't trust God's plan? It would be arrogant of us to think
we have a better plan than God, and by praying we are basically asking God to
alter his plan.
Now many Christians reading this may be thinking, “But when
I pray, I thank God for what he has given me and ask that everything happens
according to his plan”. Yes, Christians do thank God in their prayers and they
do pray for things to happen according to his plan. But I've been to church
many times, and during prayer people are constantly asking God to heal a loved
one of an illness or accident.
On a side note, what is the purpose of praying to God that
his will be done? If an all-powerful God wants his will to be done, it will be
done whether he gets encouragement from believers or not. Think about it, it
makes absolutely no sense to pray for God’s plan to happen because it is HIS
plan - Christians are basically asking him to grant his own wish! It seems
almost like people are trying to suck up to God so that he will help them later
when they really need it.

It’s odd that people who claim to have “Faith” in
God and his plan are always trying to alter it to what they feel is best for
them. However, this is not surprising, because we all want to enjoy our lives
and we’ll do just about anything we can to make it better. We also want to believe that
everything is going to be okay, and for believers it is comforting to think
their God has a divine plan.
But this is where their cognitive dissonance comes into play -
believers want to believe in these two concepts because one is comforting and
the other is a possible way to improve their life or the lives of others. If prayer worked, it would
also be the easiest way to improve our life because it requires little to no
effort at all and when given a task we usually will choose the easiest way to
accomplish it. If we believe prayer works, we feel like we did something to make a difference without doing anything at all - and this is tragic for those who need real help. As Lawrence Krauss once put it,
"If you are choking next to me and either I could preform the Heimlich maneuver or I could pray for you, which would you choose?
"If you are choking next to me and either I could preform the Heimlich maneuver or I could pray for you, which would you choose?
There is no evidence for a god, but even if there was a god
– believing that it has a divine plan and also answers our requests which would
alter his plan is completely incompatible.
