The Old Testament often describes a mundane type of life. Many times we read something like this:
“So-and-so begat so-and-so. He lived so many years and he died.” “So-and-so begat so-and-so. He lived so many years and he died.” “So-and-so begat so-and-so. He lived so many years and he died.” “So-and-so begat so-and-so. He lived so many years and he died.”
This is why our Abba Father God had his Son Jesus bring us the gospel truth of his Kingdom, as he told Moses he would in Deuteronomy 18:15-19. He said he would require us to believe it and live it. Hebrews calls this the New Covenant that Jesus is the Mediator of. It is the reality of the way God sees things, and he wants us to think his thoughts and know his ways (Isa 55:8-9). It is the reality of our Kingdom identity: who we are in Christ. It leads us into living the abundant life of Jesus (John 10:10).
The gospel is how we come to truly know our Father and his Son, know the power of his resurrection for us, the fellowship of his sufferings he endured for us, and that we are made conformable to his death (Phil 3:10). God sees us as being dead in Christ, so that we also live with him in his resurrection (Col 3:3). This is hard for us to grasp because we see ourselves as being alive, breathing, and our heart beating. But this is not life to God. The gospel propels us to come to know him and live in him. It causes us to think about heavenly things and how they govern things on earth (Col 3:2).
The gospel is how we know that Jesus abolished death for us, and gave us both (1) earthly abundant life, and (2) eternal life with him in heaven forever (II Tim 1:10). The gospel reveals God’s righteousness that is imparted to us by Jesus (Rom 1:16-17, II Cor 5:21).
We must understand ‘the word of his Kingdom’ (Matt 13:19), which is the same thing as the gospel of his Kingdom (Matt 24:14). There is no difference. The gospel is God’s revelation to us of all the benefits, glories, promises and blessings that are ours in the finished work of the cross of Jesus. This is why it is so important to him that we allow it to consume us, and that we live it. It gives us abundant life (John 10:10). It causes us to reign with Christ in our earthly life (Rom 5:17). “As Jesus is, so are we in this world” (I John 4:17).
It takes more than one lifetime to experience all that our Abba Father has for us.
