βIn hope of eternal life, which Godβ¦promised before the world beganβ (Titus 1:2).
In the Law of Moses, God promised the people of Israel that they could βliveβ (Lev. 18:5)βliveΒ eternallyβif they kept His commandments. We know thatβs what Leviticus 18:5 meant because the LordΒ quotedΒ that verse to a man seeking eternal life (Lu. 10:25-28).
But God promised us Gentiles eternal lifeΒ beforeΒ the Law, even βbefore the world began.β But unlike the promise of life He made to the Jews in the Law, He didnβtΒ revealΒ His promise to us Gentiles for thousands of years! Speaking of that promise (Tit. 1:2), Paul added,
βBut hath in due timesΒ manifestedΒ His word through preaching,Β which is committed unto meβ¦βΒ (Titus 1:3).
When God finally decided to reveal His promise to give the Gentiles eternal life, He chose Paul to break the news. The due time had finally come to disclose His promise!
But what does that phraseΒ due timeΒ mean? Well, that exact phrase is used when some unbelieving Jews were persecuting some believers in Israel, and the believers were wondering how long God would allow this to go on! God answered them,
βTo Me belongeth vengeanceβ¦ their foot shall slideΒ in due timeβ¦ the LORD shall judge His people, and repent Himself for His servants,Β when He seeth that their power is goneβΒ (Deuteronomy 32:35,36).
God told those persecuted believers, as it were, βIβll judge the unbelievers among My peopleΒ in due time,Β and the due time will come when I see that My servants (you believers)Β have no power to save yourselves from their persecution.βΒ So the phraseΒ due timeΒ refers to a time when God looks at men and sees βthat their power is gone.β This helps us understand theΒ nextΒ time the phrase appears:
βFor when we were yet without strength,Β in due timeΒ Christ died for the ungodlyβ (Romans 5:6).
The Jews had vowed they could keep the Law (Ex. 24:7), but over the next 1500 years they showed that they had no power to keep it. And when they showed that they were βwithout strengthβ to keep it, Christ died for the ungodly. But as far as anyone knew, He only died for ungodlyΒ Jews, Isaiahβs people (Isa.53:8). He only died βto give His life a ransomΒ for manyβ (Mt. 20:28), the βmanyβ in Israel,Β for that was all that God had revealed up until that time.
It isnβt until you come to Paulβs writings that you read that βChristβ¦gave Himself a ransomΒ for all,Β to be testifiedΒ in due timeβΒ (I Tim. 2:5,6). And the thing thatΒ made itΒ the due time for Paul to testify this was that thatβs when it became obvious that the Gentiles were without strength to save themselves too!
If youβre not sure what I mean by that, consider that if a Gentile wanted to be saved in time past, he had to become a JewβaΒ trueΒ Jew, aΒ believingΒ Jewβby believing onΒ the God of the Jews.Β For Gentiles, salvation was found βin the remnantβ in Jerusalem (Joel 2:32). Thatβs why the LordΒ sentΒ the remnant of the 12 apostles to the Gentiles in βall nationsβ (Lu. 24:47).
But the 12 were told to take the gospel to all nationsΒ βbeginning at JerusalemβΒ (Lu. 24:47). When the Jews in Jerusalem stoned Stephen instead of sending forth βthe word of the Lord from Jerusalemβ (Isa. 2:3), it looked like the Gentiles were going to remain without strength to get saved.
Thatβs when God raised up Paul to testify that the Gentiles didnβt have to become Jews to get the eternal life that God promised Israel in the Law, for He had promisedΒ themΒ eternal life before the world began!
Isnβt it about timeΒ youΒ received βthe promise of life which is in Christ Jesusβ (II Tim. 1:1 by believing that He died for your sins and rose again (I Cor. 15:1-4)? source
