It certainly is
Brethren, my heart’s desire and prayer to God for Israel is that they may be saved. For I bear them witness that they have a zeal for God, but not according to knowledge.
For they being ignorant of God’s righteousness, and seeking to establish their own righteousness, have not submitted to the righteousness of God.
For Christ is the end of the law for righteousness to everyone who believes.
Abraham was Called out of the world and sin by the LORD GOD
Abraham was saved thru faith in the Word that was God
God preached the (saving) Gospel to Abraham and Abraham BELIEVED and was Regenerated unto spiritual life in God.
What then shall we say that Abraham our father has found according to the flesh?
For if Abraham was justified by works, he has something to boast about, but not before God.
For what does the Scripture say?
“Abraham believed God, and it was accounted to him for righteousness.”
