But what if you sin after you believe in him? Perhaps you missed this little nugget in Scripture:
[Jesus] said to them again, Peace be with you. As the Father has sent me, so I send you. And when he had said this, he breathed on them and said to them,m Receive the holy Spirit. Whose sins you forgive are forgiven them, and whose sins you retain are retained. (John 20:21-23)So there is a need for forgiveness of sins even after accepting of Jesus.
Daniel's ninth chapter gives detailed instructions on the fate of ISRAEL, the putting an end to sin for Israel. The sixty-ninth week ended when Messiah was 'cut off'. The seventieth weeks has yet to begin while the special CHURCH AGE is open.
This is not the catholic church age, it is the Church/Bride/Body of Jesus Christ age. Under this age there is no differentiation between Jew and Gentile. When Jesus sent them forth prior to the Cross there was most definitely a difference between Jew and Gentile and Jesus confirmed this with two or three instances, such as the woman who came to Him begging for healing for her daughter.
