Was Saul of Tarsus saved under the Kingdom Gospel?
Yes, Saul of Tarsus was saved under the Kingdom Gospel by believing who Jesus was—the Son of God, the Messiah of Israel, the Promised One out of the Old Testament. That was all he understood, but it was enough because it was all God had revealed at that time.
Les teaches that even Saul of Tarsus was saved under the Kingdom Gospel, believing who Jesus was—the Son of God, the Messiah of Israel, the Promised One out of the Old Testament, coming to the Jews under the covenant promises. That's all Saul understood at that time. But that was enough, because that's as much as God had revealed at that time. Later, God would move him out among the Gentiles to enlighten him further. The same confession was made by Peter, Martha, the Ethiopian eunuch, and all the others: that He is the Christ, the Son of the Living God. But that was not enough now, so God would move him out.
