Numbers 30:2 If a man vow a vow unto the Lord, or swear an oath to bind his soul with a bond; he shall not break his word, he shall do according to all that proceedeth out of his mouth.
Keep your promises! Be a man of your word. One is not required to make a vow or swear an oath, but if he does, he must keep his promise. We do properly make vows and oaths in marriage, in court, and in legal contracts; but other than that, it is probably more prudent not make a promise we can’t or won’t keep than to make a promise and break it.
Keeping promises is vital to developing trust and to keeping relationships smooth. Marriages and families depend on it for life and wellbeing. We may take a vow, swear an oath, or make a promise for many reasons. We keep our promises because God keeps His promises to us. This is our response to His faithfulness. Faithfulness and honesty are marks of a godly man or woman who believes in Jesus. What we say matters; and God takes it seriously. The bottom line in our response to the affairs of life: we don’t make promises lightly or swear in uncertain matters, but if we do we keep our promise. Responding in faith to God’s faithfulness makes life better.
