A lot of individuals only consider Matthew 7:16-20 about others. They examine the fruits other people are bearing but forget to examine theirs. Salvation is on personal experience and not congregational. You need to ask yourself some very important questions in another know for sure if you are on your going to heaven or hell.
Do not be surprised to know that a lot of people who are in the Church, serious and tongue-speaking will go to hell.
As a matter of fact, the Lord Jesus in Matthew 7:22-23 says some who have been performing miracles will end up in hell. So, you really need to assess yourself to know for sure where you are headed.
The question you are to ask yourself is that Am I saved? Are the fruits I am bearing the type that should be produced by a person who is saved?.
We now live in a world where there are all kinds of folks who claim to be born-again Christians. They pretend to be Holy on Sunday, but on Monday morning, they will start manipulating figures in the office.
Examine yourself to be sure that you are not one of them. There are born-again prostitutes, very serious in the Church, but in their secret place, they sleep with individuals who are not their significant other and partake in all other kinds of sexual immorality.
Carry out a sincere assessment on yourself with the fear of God, fear for the doom that awaits anyone who isn't genuinely saved, and trembling at imagining yourself standing before the Almighty God on judgment day.
