Ever since about three or four months ago, I've been having doubt about the existence of God.  I'm a Christian.  Is this normal?  I don’t want Him to think I’m ungrateful or anything.  Help!
Sincerely,
Agnostically Challenged

Dear Agnostically Challenged,

Everyone faces times of doubt in their life; the key is to strengthen the weaknesses in our resolve.  Like the man who cried out, “I believe, help my unbelief!” (Mk 9:24), all Christians must recognize that faith must grow and increase over time.

Faith is the evidence of things not seen (Heb 11:1).  We can’t see God, but there is plenty of evidence that He exists.  The whole creation cries out as evidence of God’s existence (Rom 1:20).  As science and our knowledge of the natural world have increased, the proof of God’s existence has increased as well.  Answersingenesis.org is a website based entirely around the scientific proof of God’s existence.  Books like Has God Spoken? by A.O. Schnabel, Case For A Creator by Lee Strobel, and Evidence That Demands A Verdict by Josh McDowell are excellent resources that make clear the existence of the God of the Bible.  Take the time to fill your mind with information from sources like those mentioned above, and you will find yourself more confident in no time (Php 4:8).   SB
