Jesus said, "Do not give what is holy to the dogs; nor cast your pearls before swine, lest they trample them under their feet, and turn and tear you in pieces." (Matthew 7:6)
And,
"But other seed fell on good ground and yielded a crop that sprang up, increased and produced: some thirtyfold, some sixty, and some a hundred." (Mark 4:8)
Obviously He doesn't want us wasting time and effort on people who are obviously not going to be productive. That's not that we don't love them and pray for them however. But He seems to want us giving our first priority to the good soil where the seed will be productive.
So, my question is: How do you identify good soil?
As God leads us to speak we should speak.
We plant and water and God makes it grow.
Isaiah 55:11
So shall My word be that goes forth from My mouth; It shall not return to Me void, But it shall accomplish what I please, And it shall prosper
in the thing for which I sent it.
The people of Nineveh in the days of Jonah were likened to good soil but not in Jonah's eyes.
Jonah 3:4-5
And Jonah began to enter the city on the first day’s walk. Then he cried out and said, “Yet forty days, and Nineveh shall be overthrown!”
5So the people of Nineveh believed God, proclaimed a fast, and put on sackcloth, from the greatest to the least of them.
Jonah was displeased and angry.
Jonah 4:1
But it displeased Jonah exceedingly, and he became angry.
What was God's answer to the displeased and angry preacher?
Jonah 4:5-10
So Jonah went out of the city and sat on the east side of the city. There he made himself a shelter and sat under it in the shade, till he might see what would become of the city.
6And the Lord God prepared a
[a]plant and made it come up over Jonah, that it might be shade for his head to deliver him from his misery. So Jonah
b was very grateful for the plant.
7But as morning dawned the next day God prepared a worm, and it
so damaged the plant that it withered.
8And it happened, when the sun arose, that God prepared a vehement east wind; and the sun beat on Jonah’s head, so that he grew faint. Then he wished death for himself, and said, “
It is better for me to die than to live.”
9Then God said to Jonah, “
Is it right for you to be angry about the plant?”
And he said, “
It is right for me to be angry, even to death!”
10But the Lord said, “You have had pity on the plant for which you have not labored, nor made it grow, which
[c]came up in a night and perished in a night.
11And should I not pity Nineveh, that great city, in which are more than one hundred and twenty thousand persons who cannot discern between their right hand and their left—and much livestock?”
