As believers in Jesus Christ, we should be dedicated to obeying God’s word.
However, we are not to make an oath to God. The bible says in James 5:12
“Above all, my brothers, do not swear—not by heaven or by earth or by anything else. Let your “Yes” be yes, and your “No,” no, or you will be condemned.”
Nehemiah 9:38 “In view of all this, we are making a binding agreement, putting it in writing, and our leaders, our Levites and our priests are affixing their seals to it.”
Nehemiah 10:28-29 “The rest of the people—priests, Levites, gatekeepers, musicians, temple servants and all who separated themselves from the neighboring peoples for the sake of the Law of God, together with their wives and all their sons and daughters who are able to understand— all these now join their fellow Israelites the nobles, and bind themselves with a curse and an oath to follow the Law of God given through Moses the servant of God and to obey carefully all the commands, regulations and decrees of the Lord our Lord.”
As believers, we should also separate ourselves from the world and its ways and be devote to Jesus.
Romans 12:6-8 “We have different gifts, according to the grace given us. If a man’s gift is prophesying, let him use it in proportion to his faith. If it is serving, let him serve; if it is teaching, let him teach; if it is encouraging, let him encourage; if it is contributing to the needs of others, let him give generously; if it is leadership, let him govern diligently; if it is showing mercy, let him do it cheerfully.”
2 Corinthians 9:7 “Each man should give what he has decided in his heart to give, not reluctantly or under compulsion, for God loves a cheerful giver.”
The Israelite people made an oath before God to obey His commands. We are not required to make and oath, but we should be committed to obeying God’s word.
