Mankind should know that people should make a choice and should have to come to a pure belief in line with God's Wishes and not according human doctrines. Our first priority should be to please God, but all should know that without faith and by keeping to human and heathen traditions it is impossible to please God.
The apostle Paul has given all those who want to follow Jesus an exhortation, so that there should be no doubt how they have to behave and how they should all become united in the One Body of Christ.
In the world we can find a growing amount of Messianic groups. There may be seen a lot of differences in the way they are structures and hold services, but what is most important is how they want to try to the Word of God and want to be partakers of the Body in Christ, willing to be united in Christ.
