God is faithful to all of his word, his warnings and his promises

But among all these was not one of those numbered by Moses and Aaron the priest when the children of Israel were numbered in the waste land of Sinai. For the Lord had said of them, Death will certainly overtake them in the waste land. And of them all, only Caleb, the son of Jephunneh, and Joshua, the son of Nun, were still living.
Numbers 26:64-65

To be on fire for Jesus Christ is the best service we can do for the people.

Now when Israel was living in Shittim the people became false to the Lord, doing evil with the daughters of Moab:
Numbers 25:1

Through Phinehas, and because of his passion for my honour, my wrath has been turned away from the children of Israel, so that I have not sent destruction on them all in my wrath. So say to them that I will make with him an agreement of peace: And by this agreement, he and his sons after him have the right to be priests for ever; because, by his care for the honour of his God, he took away the sin of the children of Israel.
Numbers 25:11-13

Balaam’s testimony of Jesus

Even if Balak gave me his house full of silver and gold, it would not be possible for me to go outside the orders of the Lord, doing good or evil at the impulse of my mind; whatever the Lord says I will say? So now I will go back to my people: but first let me make clear to you what this people will do to your people in days to come. Then he went on with his story and said, These are the words of Balaam, the son of Beor, the words of him whose eyes are open: He says, whose ear is open to the words of God, who has knowledge of the Most High, who has seen the vision of the Ruler of all, falling down and having his eyes open: I see him, but not now: looking on him, but not near: a star will come out of Jacob, and a rod of authority out of Israel, sending destruction to the farthest limits of Moab and on the head of all the sons of Sheth.
Numbers 24:13-17

Sin Judged

Then the people came to Moses and said, We have done wrong in crying out against the Lord and against you: make prayer to the Lord to take away the snakes from us. So Moses made prayer for the people.
Numbers 21:7
