Many people are coerced into making confessions of faith. They say the words, but they don't mean it. They acknowledged Jesus in their minds, but their hearts are still set on the things of this world. We need to examine ourselves. Do you know for sure that Jesus is living in you?
2nd Corinthians 13:5
Examine yourselves as to whether you are in the faith. Test yourselves. Do you not know yourselves, that Jesus Christ is in you?--unless indeed you are disqualified.
Examine yourself. Have you received Jesus in your heart? Can you say with absolute certainty that you have given your life to Jesus? If you have never received Jesus in your heart, you have not received the free gift of salvation.
