(Jesus said) Therefore I tell you, every sin and blasphemy will be forgiven people, but the blasphemy against the Spirit will not be forgiven.
Many people become worried i case they have committed the unforgivable sin. It is important therefore that we think about this and really understand what Jesus means when he speaks about sinning against the Holy Spirit. Remember that the great work of the Holy Spirit is to give people a clear view of who Jesus is, and to call people to the salvation that is found only in Jesus Christ.
When someone comes to know all about Jesus but who persistently and deliberately refuses to believe in him for salvation then that person will not be forgiven. If someone is worried that they have committed this sin then that is a sure sign that they have not committed it. It is unbelievers "who deliberately and unchangeable reject the ministry of the Holy Spirit in calling them to salvation who commit such a sin. Christians do not commit an unforgivable sin.
It is a terrible thing when someone sets out deliberately to set his heart and mind against God and against Jesus Christ and the work of the Holy Spirit. Such a person will have to stand face to face with God one day when he will find out the awful truth that he will have to spend eternity suffering God's rejection of him as he had rejected God.
Dear Lord, help me to pray for my friends who as yet reject the Gospel. Amen.
