To me, my faith in God, its a difference like day and night. Adopting a theistic world view, i can know God, and experience his grace and love of a loving father. Its a joy to be able to witness to others about the greatness of God. In that way, i am making a difference in this world, and my life has also value for others. It means loving and being loved by others. Furthermore, i find meaning , self worth, and ultimately it makes a difference, how i live, and who i am, and what i do today, has significance and consequences also in eternity. My life is not doomed when i die, rather i have the perspective of living eternally with God. So belief in God gives me hope for a eternal life in heaven. Furthermore, i find peace with God through the forgiveness of my sins, through Christ's death on the cross. Without faith in God, there is no hope of deliverance of unjustice and evil. Nor are there objective moral values. Everything becomes subjective and relative, and depends entirely on each individuals standpoints. Ultimately, there is no good, and no evil. There are just different viewpoints and standards based on personal preferences. Furthermore, the existence of the universe and life makes sense and its existence is explained in a satisfiying manner through a creator. In a broader sense, Christianity has shaped western civilisation in many ways for the better. The Bible itself is responsible for much of the language, literature, music and fine arts we enjoy today as its artists and composers were heavily influenced by its writings. The liberties and human rights of secular governments , freedom and rights of the individual, and so the criminal and justice system are direct consequence of the bible, and so the belief that man is accountable to God and that the law is the same regardless of social position, power and wealth. The education system, care of orphans and the elders, and hospitals goes back to the spread of monasteries, which were taking care of the general population. Science began to flourish in the western world, like Occam's razor in the twelfth century , and many science fathers, like Galilei, Newton, Volta, Ohm, Ampere, Kelvin, Faraday etc. were all Christians. There are many other things, but this is just to name a few.
