We cannot prove the existence of God, but there are many reasons why belief in God is reasonable. The first is that nothing science has discovered explains the existence of the universe. Yet the universe has a beauty and an order that suggests that a rational mind lies behind it all. Just as the existence of a computer demonstrates that there is someone who invented it, so the world in all its beautiful complexity points to the existence of a Creator, God.
One of the most compelling reasons to believe in God, Jesus and the Holy Spirit is to listen to, or read, personal testimonies of how “coming to faith” has transformed individuals lives for the better.
