Matthew 5:43-48 You have heard that it was said, "YOU SHALL LOVE YOUR NEIGHBOR and hate your enemy.' But I say to you, love your enemies and pray for those who persecute you, so that you may be sons of your Father who is in heaven; for He causes His sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous. For if you love those who love you, what reward do you have? Do not even the tax collectors do the same? If you greet only your brothers, what more are you doing than others? Do not even the Gentiles do the same? Therefore you are to be perfect, as your heavenly Father is perfect.
>This is the Mystery Age of the Church, the body of Christ. Israel is not grafted in again. We are joint heirs with Christ. If we are in fellowship with Christ, we are already sanctified, we do not have to work at that. "We're in." Now, evil company corrupts good morals, so whoever we greet, we have already decided not to leave the company of Christ. Whatever company we are in, it is always right to speak good of His name. The power of God in this age is the Good news of Jesus Christ. Jesus is Lord.
