“Thou shalt not take the name of the Lord thy God in vain: for the Lord will not hold him guiltless that taketh his name in vain…” (Deut. 5:11).
In everything, we are to bring greater glory to God. However, when we engage in invoking the name of the Lord and follow it with lies, we are diminishing the authority, influence and value of God’s name. We must take into consideration that this is occurring in the eyes of a secular society whose cynical worldview and skepticism are prevalent and who is actively seeking for reasons to not believe in the God (Jesus and Holy Spirit) of the Bible.
By invoking God’s name in making an oath, we are obligating ourselves to a commitment to speaking the truth. When we violate the oath with lies, we are providing the cynic and the skeptic with the very reason for which they seek to not believe in the TRUE God of the Bible. If they were to leave this life without knowing God, they will be eternally lost and their blood will be required at our hands (Ez. 33:6).
