So far, we are also fulfilling this promise. Isn't there a similar promise in the gospels?
When we pray for God's kingdom and righteousness, God will also give us what we need.
As for what happens to us, sometimes we can ask God about the future, or ask God to prescribe his actions.
His works are righteous, and his throne is established by lovingkindness, and righteousness is carried out.
Isn't this the god we believe in?
God has the same nature from beginning to end, except that he has no shadow of turning. We are called people who know God, truly know God and grow up in truth.
If you have to explain, there is no such thing, but you can check all God's actions in the Old Testament and the New Testament, and you can also check God's personal experience, and you will know that we believe in such a God. He is the master of all things.
