In regards to faith, I do like the author of Hebrews from Ch. 11 v.1 :
“Now faith is the assurance of things hoped for, the conviction of things not seen.” (ESV)
I do like Greg Koukl’s description that faith is “active trust”. Too often these days the word faith is coupled with “leap of” or “blind” and it implies that if you have faith or “you just gotta have faith”, that it is somehow antithetical to reason. In reality, Biblical faith, faith in Jesus Christ, is an assurance based on evidence, leading to knowlege, out of which comes faith – that active trust that Greg talks about. It is also important that you not only have faith itself, but that your faith is put in something (someone) whom you can trust. In other words, it is the object of your faith that is important, not merely the faith itself. If I place my trust in something that turns out to be untrustworthy, my faith has been misplaced. That is why my own faith is born out of evidence and knowlege and not out of a subjective feeling or some sort of experience that I’ve had.
I’ll leave it at that and invite comments.
