What does it mean to live in faith?

I've been contemplating a lot with that statement. What does in mean to live in faith? I will not explain everything in this one blog. However, God is really testing my faith in Him. I want to live my life in faith in God. I know that He will take care of me and my future wife (and kids in the future). There are so many uncertainties with less than 2 weeks away from the wedding. But I know that God will provide all the necessary things for my family in His time. I believe God is making me trust only in Him. Please continue to pray that I will not lose faith in God.
