New Covenant Equivalent
Do not blaspheme:
“For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies” (Matthew 15:18, KJV).
Maintain a Godly testimony in everyday affairs and responsibilities:
“Let as many servants as are under the yoke count their own masters worthy of all honour, that the name of God and his doctrine be not blasphemed” (I Timothy 6:1, KJV)
Do not make vows:
“Again, you have heard that the law of Moses says, ‘Do not break your vows; you must carry out the vows you have made to the Lord.’ 34 But I say, don’t make any vows! If you say, ‘By heaven!’ it is a sacred vow because heaven is God’s throne. 35 And if you say, ‘By the earth!’ it is a sacred vow because the earth is his footstool. And don’t swear, ‘By Jerusalem!’ for Jerusalem is the city of the great King. 36 Don’t even swear, ‘By my head!’ for you can’t turn one hair white or black. 37 Just say a simple, ‘Yes, I will,’ or ‘No, I won’t.’ Your word is enough. To strengthen your promise with a vow shows that something is wrong” (Matthew 5:33-37, NLT).
“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” (James 5:12, NIV).
Avoid Insincerity in lifestyle, seeking praise of men and making God’s name meaningless:
“You who brag about the law, do you dishonor God by breaking the law? As it is written: “God’s name is blasphemed among the Gentiles because of you.”
“A man is not a Jew if he is only one outwardly, nor is circumcision merely outward and physical. No, a man is a Jew if he is one inwardly; and circumcision is circumcision of the heart, by the Spirit, not by the written code. Such a man’s praise is not from men, but from God” (Romans 2:23-24; 28-29, NIV).
“Be careful not to do your ‘acts of righteousness’ before men, to be seen by them. If you do, you will have no reward from your Father in heaven. So when you give to the needy, do not announce it with trumpets, as the hypocrites do in the synagogues and on the streets, to be honored by men. I tell you the truth, they have received their reward in full. But when you give to the needy, do not let your left hand know what your right hand is doing, so that your giving may be in secret. Then your Father, who sees what is done in secret, will reward you” (Matthew 6:1- 4, NIV -see also verses 5-18).
