I really believe with all my heart that every blood-bought, born again Believer should make a pilgrimage to Israel. It is not just a vacation, nor just an experience, rather it is an investment in your faith.
You cannot go to Israel and come back the same. What happens when you go to Israel is that your Bible is turned into a 3-dimensional, multi-colored, high-definition encounter. Going to Israel will help you to know God all the more.
