Repent & be Baptized IS NOT the message for today's Body of Christ
Jesus, the Baptist & the 12 preached the Gospel of the Kingdom.
The kingdom offer required NATIONAL repentance (
Matt 3:2 &
4:17), receiving the King (J 1:11) & faith in His identity (
Jn 8:24).
The kingdom could not be established without the NATION receiving the King, because the Davidic kingdom is a NATIONAL covenant (2 Sam 7, Ps 89, Isa 9, Jer 23, Ezek 37).
A glimpse of God's promised coming Kingdom to Israel:
2 Sam 7:12–13,
1 Chron 17:10–14,
Isa 9:6–7,
11:1–9,
Dan 2:44,
7:13–14,
Mic 4:1–5,
Zech 14:1–21,
Luke 1:32–33.
All the above OT verses are coming-kingdom promises God made to Israel's fathers (
Rom 15:8). They are the necessary context for understanding Jesus' kingdom message (
Matt 3:2).
This kingdom message was preached only to Israel ONLY, NEVER to Gentiles. It did not include/reveal the cross, the resurrection as a saving message, the Body of Christ, or justification by faith apart from the Law, because the kingdom message was tied to Israel's covenant promises & NATIONAL repentance.
Acts 2 exposes Israel's continued rejection: Peter says, ""you have taken and by wicked hands have crucified & slain"" (
Acts 2:23). That is not national repentance. That is national guilt.
Acts 10 exposes God saving Gentiles WITHOUT Israel: No kingdom, No national repentance, No water baptism, No Law, No Israelite mediation, No ""kingdom at hand"" message.
God saves Gentiles by hearing (
Acts 10:44), by faith (
Acts 15:9) without repentance, water baptism or circumcision
Acts 2 shows Israel rejecting the King & Acts 10 shows God saving Gentiles without Israel-proving the kingdom message depended on the nation, while the grace message bypasses the nation entirely.
The 2 messages are not the same. The Kingdom message depends on Israel receiving her King. The Grace message bypasses Israel entirely & depends on faith alone.
The gospel message today is Here:
1 Cor 15:
3 That Christ died for our sins according to the scriptures;
4 That he was buried, and that he rose again the third day according to the scriptures:
Rom 10:
9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
10 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
11 For the scripture saith, Whosoever believeth on him shall not be ashamed.
12 For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him.
13 For whosoever shall call upon the name of the Lord shall be saved.
