- Definition from Merriam-Webster: “firm in adherence to promises or in observance of duty”
- “firm in adherence to promises…” speaks most clearly to how God is faithful.
- “firm in…observance of duty” speaks most clearly to how we can be faithful.
- In Rom 15:7-13, Paul does not use the word “faithfulness” but he does show that fulfillment of the messianic plan was to the Jews a matter of God’s faithfulness while to the Gentiles it was a matter of His mercy. This is because, of course, God’s promises were given to the Jews – not the Gentiles. The Gentiles were mentioned in the promises, but the promises were given for safekeeping until their fulfillment to one nation – Israel. Now all nations have them in writing, and this has been the case ever since Acts 10 when Peter first preached to the Gentiles.
- The entire enterprise of science is built upon God’s faithfulness. Scientists just don’t call it that; rather, they call it the laws of nature as if laws could exist without someone enacting and upholding them.
