Can you pick olives from a fig tree or figs from a grapevine? No, and you can't draw fresh water from a salty pool.
If you are wise and understand God's ways, live a life of steady goodness so that only good deeds will pour forth. And if you don't brag about the good you do, then you will be truly wise!
But if you are bitterly jealous and there is selfish ambition in your hearts, don't brag about being wise. That is the worst kind of lie.
For jealousy and selfishness are not God's kind of wisdom. Such things are earthly, unspiritual, and motivated by the Devil.
For wherever there is jealousy and selfish ambition, there you will find disorder and every kind of evil.
But the wisdom that comes from heaven is first of all pure. It is also peace loving, gentle at all times, and willing to yield to others. It is full of mercy and good deeds. It shows no partiality and is always sincere.
And those who are peacemakers will plant seeds of peace and reap a harvest of goodness.
