Faith

It is simultaneously easy and impossible to believe in God. The thinking human realizes the physical impossibility of God's existence outside of the universe, in a place where He could have created our universe. But that same human must see the necessary existence of some force to create the universe we exist in. No real thing can come from true nothingness. Our physical reality is like a dream without God as an explanation. Dreams don't have beginnings, rather they are movies which we are viewing already in progress. No matter how early we can go with scientific exploration, something had to have always existed and this could have been physical matter, but the chain of events that followed the initial existence of the first physical particle was set in motion by some outside force and God, in some form, is that outside force.

Faith is a crutch that verifies existence and makes existence easier to bear. Faith can shoulder our everyday burdens. Faith is tested in death, the death of others, of those close to us. Faith makes death bearable for those who have it because it lets the cliche "They are in a better place with God" apply. This is delusion. This belief that God wants to have our loved ones with Him falls apart in the fact that dying people cry. God's will can not override that of man.
The belief that death is the end of all life and that the universe does not care may not be delusional, but is far less happy and can not really be the philosophy of a happy person. Many people say they believe this, say they understand the indifference of the universe and the triviality of live. Those who deny meaning to life are dissatisfied with their own.
Those people who choose not to explain their life in the context of God and accept life as it is and do not fear it enough to place themselves in one of the two extremes are the ideal. Faith in its ideal form simply accepts life with the hope that there is a plan for life set in motion by God. The confident, unafraid life is spent in the same way, only the hope comes from within.
Life in the context of God is not wrong. Life becoming God and blindly praying that God will change your life for the better is the problem of faith. Theistic existentialism.
