Here are some of my favorite Christian quotes about faith. If you're having a tough time, just think about these.
"Faith is to believe what we do not see, and the reward of this faith is to see what we believe." - Augustine
"To be an atheist requires an infinitely greater measure of faith than to receive all the great truths which atheism would deny." - Joseph Addison
"Faith is the ability to see the invisible and believe in the incredible and that is what enables believers to receive what the masses think is impossible." - Clarence Smithison
And He said to them, "Because of the littleness of your faith; for truly I say to you, if you have faith the size of a mustard seed, you will say to this mountain, 'Move from here to there,' and it will move; and nothing will be impossible to you. - Jesus
"Let God's promises shine on your problems." -Corrie Ten Boom
"Take the first step in faith. You don't have to see the whole staircase, just take the first step." -Martin Luther King, Jr.
"Faith moves mountains, but you have to keep pushing while you are praying." - Mason Cooley
