As a pastor, I believe the most common question asked is how do you know that someone or even yourself is truly saved or a Christian.
The Bible tells us in Matthew chapter 7:15-20 “Beware of false prophets, who come to you in sheep’s clothing, but inwardly they are ravenous wolves, you will know them by their fruits. Do men gather grapes from thorn bushes or figs from thistles? Even so every good tree bears good fruit, but a bad tree bears bad fruit. A good tree cannot bear bad fruit nor can a bad tree bear good fruit every tree that does not bear good fruit is cut down and thrown into the fire therefore by their fruits you will know them.
So I would say give yourself an exam just as you do others and ask yourself this does my life bear the fruit of a good soldier.
