For whoever does the will of my Father in heaven is my brother and sister and mother. Furthermore, sin can lead to spiritual death in the life of a Christian. There is only one remedy for this spiritual pollutant, that is, the precious, cleansing blood of Jesus Christ. If you are not following Jesus at this moment, then you desperately need to become a Christian. If you were once a Christian, but since have died spiritually because of sin, then you desperately need to repent and get saved again.
Salvation is as important as eternity is long.
Your most valuable possession is your eternal soul. Don't take a chance with it. Jesus is the only Savior. Jesus is your only hope of salvation. He is patient with you, not wanting anyone to perish, but everyone to come to repentance.
