I believe that every human being has faith in something or someone, whether it be in God, themselves, a philosophy, etc.
My faith is in Jesus Christ as my substitutionary atonement, satisfying a holy God's judgment upon me as a sinner, allowing me to stand blameless before God on the merits of Christ alone.
From this past Sunday's sermon:
Which of the following takes greater faith?
In the beginning...God created all things from nothing
In the beginning...there was nothing and then it (nothing) exploded!
