A believer walks in the faith of Yeshua.
The faith of Yeshua is the steadfastness (the Hebrew word, emuwna) of God.
There can be no faith without steadfastness, and the steadfastness must be to the end.
There is no falling short in the steadfastness of God.
If I say a believer is steadfast, the believer must continue in the faith up to the point such a statement is made.
If a say the believer was steadfast, but is no longer, there is no longer “faith” or steadfastness. He or she has fallen from grace. Perhaps God will have mercy.
If one of the nations (Gentiles) is a Christian, he or she is certainly “messianic” in the sense of accepting by grace and the will of God, that Yeshua ha Mashiach has come in the flesh, died for our sins according to the Old Testament, was buried and rose again the third day according to the Old Testament. The believer accepts by grace that Mashiach has come by the one true gospel, and awaits for the Mashiach to come a second time, whether at the end of life in a generation that is not of judgment, or in the final generation at the judgment when the time of the nations in fulfilled. We abide in this generation now. Yeshua will come with power to fight that final battle against the adversary, and sin and death. He comes in judgment against the nations and mercy and grace extended towards Yisrael and the saved, for it is written, “all Yisrael shall be saved”. And then in the Mashiach all are made alive, each person in God’s own order. Then every knee shall bow and every tongue confess that Yeshua is Lord to the glory of God the Father.
If this is what “messianic” means, as I so write, then whether of the nations or of Yisrael, all are messianic. There is no Messianic Jew to the exclusion of the nations, as there is no messianic Gentiles to the exclusion of the Jew – for we are all one in the Mashiach, the chosen ones of God by His will and grace to accept the one true gospel.
I mark this writing by the one true gospel, and the one true gospel is the Mashiach, Yeshua of Nazareth, died for our sins according to the Old Testament, He was buried and He rose again the third day according to the Old Testament. (Luke 24, 1 Cor 15:-16) The testimony of two confirm the fact – the Father and the Son.
Father, we have sinned greatly against you and are not worthy of the least of your mercies. Save us by your grace, not because of anything we have done, but through your righteousness in the Mashiach. I know that in this flesh dwelleth no good thing, but in the resurrection of Yeshua ha Mashiach dwelleth all good things. I and the chosen ones judge not ourselves. For who is worthy of the riches of the Mashiach. But you have chosen us not for anything we have done before we did any evil or good, but for your good pleasure. God we ask for the life of all people in the end in the name of Yeshua. Amen.
