Faith in God is an amazing, and difficult, thing. We put our faith in other people or in other things because we have experienced them, or witnessed them to be true. We know that people have flown in planes and survived, therefore we know it's safe. We've sat on chairs before, therefore we trust similarly structured objects to also hold our weight when we sit on them. We've seen others display their love for us, therefore we trust that that love will continue. Yet there is nothing concrete we can use to explain our faith in God. We have His word, but that relies on faith that it is truly inspired. We have answered prayers, but that depends on faith that it truly was God's work and not just chance.

1 Peter 1:8 - "And though you have not seen Him, love Him."
James 1:6 - "But he must ask in faith, without any doubting."

Faith in God is a constant, active thing. it's not a lackadaisical second thought, but requires determination to declare that although I cannot see, I believe. And not only believe, I love. This is not phileo love, which says that I am fond of God. But is agapeo, the verb form of agape. Do I truly have a brotherly, benevolent love toward God, or is it just an appreciative fondness?

Hebrews 1:1,6 - "Now faith is being sure of what we hope for and certain of what we do not see. And without faith it is impossible to please Him, for he who comes to God must believe that He exists, and the He rewards those who earnestly seek Him."

Faith, once accepted, can be freeing. It is not necessary to know God before we can receive salvation, it is only necessary to accept that He can offer salvation, and admit we need it. In fact, before we are saved, it is impossible to know God, because we do not have the spirit of God. "For who among men knows the thoughts of a man except the spirit of the man which is in him? Even so, the thoughts of God no one knows except the Spirit of God. " (1 Corinthians 2:11). When we are saved, the Spirit of God dwells in us (1 Corinthians 3:16). The Spirit teaches us (Luke 12:12, John 14:26). The Spirit reveals God's wisdom. (1 Corinthians 2:6-10)
