Messianic-Judeo-Christianity, or Messianic Judaism, is the merger of modern day Christianity, with elements of Jewish terminology and heritage. A misunderstood concept, which combines the most sacred gift of Jesus Christ, with the abundance of our Hebraic roots.
Why ? Because Jesus, Yeshua in Hebrew, was Jewish when he was on earth, and through him we are grafted into the " good olive branch " , which is Israel ! , Romans 11:17-26
So Abraham also believed God, and it was credited to him as righteousness. Know then, that those who have faith, are the children of Abraham ! , Galatians 3:6-7
