The entirety of the Scriptures is one of inclusion into the covenant. The one covenant of YHVH and His people. The House of Israel, set apart for His kingdom. There is no “new” dispensation.
Isaiah 56:6-7 (HCSB)
6 And the foreigners who join themselves to the Lord
minister to Him, love the name of Yahweh
and become His servants,
all who keep the Sabbath without desecrating it
and who hold firmly to My covenant—
7 I will bring them to My holy mountain
and let them rejoice in My house of prayer.
Their burnt offerings and sacrifices
will be acceptable on My altar,
for My house will be called a house of prayer
for all nations.”
Exodus 12:49 (HCSB)
“The same law will apply to both the native and the foreigner who resides among you.”
Romans 11:17-23 (HCSB)
17 Now if some of the branches were broken off, and you, though a wild olive branch, were grafted in among them and have come to share in the rich root of the cultivated olive tree, 18 do not brag that you are better than those branches. But if you do brag—you do not sustain the root, but the root sustains you. 19 Then you will say, “Branches were broken off so that I might be grafted in.” 20 True enough; they were broken off by unbelief, but you stand by faith. Do not be arrogant, but be afraid. 21 For if God did not spare the natural branches, He will not spare you either. 22 Therefore, consider God’s kindness and severity: severity toward those who have fallen but God’s kindness toward you—if you remain in His kindness. Otherwise you too will be cut off. 23 And even they, if they do not remain in unbelief, will be grafted in, because God has the power to graft them in again.
We MUST come to the realization that there is ONE pathway to the Kingdom of Heaven and it is the design of YHVH and not the desires of men.
