I am personally most stricken by the motivation that drove Rahab's faith. Having virtually no background in the Hebrew's religion, she knew little about Joshua's God. She DID, however, know that He had miraculously parted the Red Sea earlier for these people, so she was convinced that crossing the Jordan and taking her city Jericho would be no problem for such a powerful God.
The simple fact is this: Rahab was deeply, deeply AFRAID, for herself and her family. She feared the upcoming judgment of God, and this fear drove her to make a radical decision to follow this God........even if it meant an act of treason against her own country! Her motivation was intensely strong, and she became willing to do whatever it took to escape God's judgment.
Let's not discount Rahab's motivation. Her decision to believe and follow God saved herself and her entire family. We should all remember the words of Proverbs 1:7, which says, "The fear of The LORD is the beginning of knowledge (wisdom)". If you are experiencing a sense of dread at facing the Lord someday soon, follow Rahab's example and do whatever it takes to follow Jesus now!
