In the second and third chapter of the Bereshith (the book of the beginning) we find that God, Who had made man in His image, brought a helper for the ish or man so that they could live together in a bond of union, related to the other living beings and to the Most High Elohim, in a state we now call marriage.
In the world of Christians and Muslims there are those who may think the Torah is not for them and that they do not have to keep to the Laws of God any more. Some even prefer to follow the laws of their religious group as if that is more important than following the Laws of the Set-apart Scriptures. The world received a Sent one from God who came to give the proper, God-intended interpretation of the Torah! People do have to come to recognise that sent one from God and have to follow his teachings, with the knowledge that he is the Way to God. That sent one from God also expressed his believe in his heavenly Father Who is the Divine Creator all should come to accept as their loving Father as well. He is The One Who knows our heart and Who has provided for us a manual for our life which also explains His Plan. That manual is the Torah, we all should to favour as our most important Guide for our life.
