But most of all, my brothers and sisters, never take an oath, by heaven or earth or anything else. Just say a simple yes or no, so that you will not sin and be condemned.
Are any of you sick? You should call for the elders of the church to come and pray over you, anointing you with oil in the name of the Lord. Such a prayer offered in faith will heal the sick, and the Lord will make you well. And if you have committed any sins, you will be forgiven.
Confess your sins to each other and pray for each other so that you may be healed. The earnest prayer of a righteous person has great power and produces wonderful results.
Don’t copy the behavior and customs of this world, but let God transform you into a new person by changing the way you think. Then you will learn to know God’s will for you, which is good and pleasing and perfect.
