Most important, my brothers and sisters, never make a solemn pledge—neither by heaven nor earth, nor by anything else. Instead, speak with a simple "Yes" or "No," or else you may fall under judgment.
If any of you are suffering, they should pray. If any of you are happy, they should sing.
If any of you are sick, they should call for the elders of the church, and the elders should pray over them, anointing them with oil in the name of the Lord.
Prayer that comes from faith will heal the sick, for the Lord will restore them to health. And if they have sinned, they will be forgiven.
For this reason, confess your sins to each other and pray for each other so that you may be healed. The prayer of the righteous person is powerful in what it can achieve.
Elijah was a person just like us. When he earnestly prayed that it wouldn't rain, no rain fell for three and a half years.
He prayed again, God sent rain, and the earth produced its fruit.
My brothers and sisters, if any of you wander from the truth and someone turns back the wanderer,
recognize that whoever brings a sinner back from the wrong path will save them from death and will bring about the forgiveness of many sins.
