The final exam you've been dreading is here. You haven't studied, but if you fail, you're dead meat. Your teacher passes out the test. But stapled to the test is a sheet with all the answers on it!
God has given us a similar test. It's called life. And it's the toughest test we'll ever face. The best part about it is that He's given us all the answers! The Bible isn't just a boring history book, it's every answer we'd ever need to pass the test. Some will pass the test of life, some will fail.
Keep reading if you want the answers to the test...
The first and most obvious reason people might doubt they are Christians is because they are not. If there has been no lifestyle change since your commitment, there could be cause to wonder.
The second reason people may doubt they are saved is because they have been told that they will never know for sure until they get to heaven. I was taught this erroneous idea as I was growing up. "You'll never know until judgment day, and then...surprise!" I remember asking one of the clergy of my church about this. He replied, "I guess it boils down to this Pete -- if you end up in heaven, you'll know that you were saved all along."
BUT, "What if I end up in hell?" "Then you'll know that you weren't saved." Excuse me, but isn't it a little too late to find out?
You Have Sinned
Recognize that you've sinned and ask God to forgive you. The Bible says that if we confess our sins, He will forgive us (I John 1:9).
Turn From Your Sins
Repent of your sin with God's help and grace (Acts 3:19).
So, you gave your life to God once upon a time. You went up front, prayed the prayer and cried the tears. But now you're barely even going to church. You never read your Bible and rarely do you pray. You've fallen back into your old life; you're hanging out with all of the friends you used to party with.
