Doubt is often hostile towards faith, but sometimes it is also a normal part of faith. The some of the greatest people in the Bible had moments of doubt. I remember how Abraham laughed at God when he heard that his wife was going to have a child at 90 years of age. Or how John the Baptist asked Jesus if He was really the Messiah. Remember this: Always take your doubts to Jesus. Talk to Him about questions you have. He can handle it.
" Now faith is confidence in what we hope for and assurance about what we do not see." ( Hebrews 11:1)
