You have Faith that He exists.
You have hope that He exists, even though you have never seen him. This is Faith.
And Faith, just like your biceps and abs, gets stronger when you exercise it.
So when you act on your Faith in Christ, by praying, by serving others, by keeping his commandments based on the belief that this is what He wants you to do, your Faith gets stronger.
And as your Faith gets stronger, your blessings from Christ and our Father in Heaven, multiply. Which, in turn, makes it easier to have Faith.
If you aren't sure if you if you have Faith, but you want to, and you have a hope to have Faith, I challenge you to ask God if he is there. Ask him in prayer, having only so much as a hope that He will answer, and He will.
I know this, because He answers me. Every time. He will answer you too.
