Having faith in God is not always concerning what we hear in church, but it's a day by day thing.
Observe everything on earth, the sun, the trees and our life, then we can see so many evidences of all kinds of things and wisdom. The Bible says that the heavens declare the glory of God. All things in the world are created for different purposes and they are created, they are beautifully and wonderfully made. I agree that there is no God.
God is meaningless. Looking at the creation, this makes us more to believe in God. Romans 1:20 also says that the beginning of the world, that the creation of God has been visible. God has revealed himself through the creation.
There are numerous occasions where we might feel lost, but the Bible also provides us with clear picture of everything. In addition, when we have faith with God, our lives are being transformed. Those who are addicted or hopeless can transform their lives.
This almost says that God is really working. In Hebrews 11:6, it says that we must believe in God, because it is the word of who we diligently seek. God made us promise that we must seek Him. If you don't experience the love and kindness of God, you might not know that God exists, but we all have experienced the mercy of God in our lives.
That is why it is good to believe in God. God exists and we can trust Him always to always show up in our lives when we need Him.
