“Offer unto God Thanksgiving; and pay your vows unto the most high.” (v.14)
There are many things one could offer to God, and from many different motivations. But the one "offering" that is always acceptable to God, is praise and thanksgiving out of a pure heart. Scripture tells us to; "continually offer to God a sacrifice of praise, that is, the fruit of our lips giving thanks to his name” (Hebrews 13:15). This is so easy to do, and is an incrediable witness when done spontaneously with a sincere heart, as it glorifies God in our daily lives.
The payment of our vows mentioned in the second part of our text, is simply following through on what we pledge to do in His name. Being men and women of our word so to speak. Therefore, it is always good to “look before we leap”, and make sure that what we commit to (in His name), we can follow through with.
These simple courtesies of being thankful and dependable to our LORD show our faithfulness in the small things, and demonstrate that we are capable of more responsibilities. Therefore, “Let your ‘yes' be ‘yes', and your ‘no' be ‘no’" (Matthew 5:37), when considering your service to Him.
The Truth: "Well done, thou good and faithful servant. Thou hast been faithful over a few things. I will make thee ruler over many things.” (Matthew 25:21)
