1. Prayer is effective
Therefore, confess your sins to one another and pray for one another, so that you may be healed. The prayer of a righteous person is very powerful in its effect. Elijah was a human being as we are, and he prayed earnestly that it would not rain, and for three years and six months it did not rain on the land. Then he prayed again, and the sky gave rain and the land produced its fruit.
2. An example from Job
After the Lord had finished speaking to Job, he said to Eliphaz the Temanite: “I am angry with you and your two friends, for you have not spoken the truth about me, as my servant Job has. Now take seven bulls and seven rams, go to my servant Job, and offer a burnt offering for yourselves. Then my servant Job will pray for you. I will surely accept his prayer and not deal with you as your folly deserves. For you have not spoken the truth about me, as my servant Job has.” Then Eliphaz the Temanite, Bildad the Shuhite, and Zophar the Naamathite went and did as the Lord had told them, and the Lord accepted Job’s prayer.
3. An example from Abraham
Now return the man’s wife, for he is a prophet, and he will pray for you and you will live. But if you do not return her, know that you will certainly die, you and all who are yours.”
Then Abraham prayed to God, and God healed Abimelech, his wife, and his female slaves so that they could bear children, for the Lord had completely closed all the wombs in Abimelech’s household on account of Sarah, Abraham’s wife.
4. Shift your priorities
Trust in the Lord and do what is good; dwell in the land and live securely. Take delight in the Lord, and he will give you your heart’s desires. Commit your way to the Lord; trust in him, and he will act, making your righteousness shine like the dawn, your justice like the noonday. Be silent before the Lord and wait expectantly for him; do not be agitated by one who prospers in his way, by the person who carries out evil plans. Refrain from anger and give up your rage; do not be agitated — it can only bring harm. For evildoers will be destroyed, but those who put their hope in the Lord will inherit the land.
“Truly I tell you, the one who believes in me will also do the works that I do. And he will do even greater works than these, because I am going to the Father. Whatever you ask in my name, I will do it so that the Father may be glorified in the Son. If you ask me anything in my name, I will do it. “If you love me, you will keep my commands.
