May God bless this effort to spread His word in the Kingston area!

The text is in some ways akin to this: "...For it is impossible for those who were once enlightened, and have tasted the heavenly gift, and have become partakers of the Holy Spirit, and have tasted the good word of God and the powers of the age to come, if they fall away, to renew them again to repentance, since they crucify again for themselves the Son of God, and put Him to an open shame." (Hebrews 6:4-6). If one sins (and continues therein), they cannot come to repentance, and can never receive forgiveness. To perpetuate sin brings with it condemnation. Neither text infers that one can commit a sin which can never be repented of or forgiven. Both texts deal with unbelief in the heart.

Acts 13:39 reads, "...by him all who believe are justified from all things." Amen!! If we believe in the Lord, He is able to justify us. However, it should be noted that the questioner has left out the latter portion of this verse. It goes on to read, "...from which you could not be justified by the law of Moses." Contextually, the apostle is not dealing with the blasphemy against the Spirit, but the weakness of the law of Moses to deal with sin (it clearly revealed it, but no provision was made for forgiveness), and the strength of faith in Christ to cleanse us of all unrighteousness.
