For starters, forget about what you have heard for, or against the existence of God. Blaze your own path with a personal mission to find the truth about God. You need to do this to base your attitude toward God on actual experiences in your life, rather than only what you hear.
The difference between humans and lower animals is we are aware we shall eventually die. To allay the fear of death, some argue death is the end of life. Consequently, they tell us to eat, drink and be merry for tomorrow we are dead. They reject the existence of the human soul, retorting how could they believe the soul exists when they cannot see it.
But there is a reason they don't see the soul. And it is that the soul is a spirit. By elevating their spiritual consciousness they would experience the soul acting in their lives, and understand the purpose of death.
Death is a transition from physical life to spiritual life. It ends one form of life in order to begin another form of life. Which is why its important to know what would happen to us after death. The type of life we shall have after death is fully explained in the gospel.
Certainly, agreeing with the gospel doesn't mean blindly accepting that God exists. It means searching for proof that God exists. This is where many believers fall short. They give up too easily searching for proof that God exists.
Meanwhile, the means to prove that God exists have been with us as long as the gospel has. In Matthew 5:8 Jesus said, "the pure in heart shall see God," to press home the point that in order to see God we should purify our hearts.
Paul teaches us how to purify our hearts when he spoke about the Gentiles in Acts 15:6-9, "He [God] made no distinction between us and them, for he purified their hearts by faith." By faith our hearts are purified to enable us to see God. Read more about the power of faith at www.squidoo.com/meaning-and-application-of-faith.
