As said earlier, faithfulness is one of the moral attributes of God which describes His very nature. God, therefore, expects that believers demonstrate this attribute of faithfulness in every area of their lives. A person with a faithful heart exhibits the obedience and practice of the moral code of ethics, values and precepts from God’s word. Faithfulness in interpersonal relations will produce honour, truth and reliability. Our faithfulness must be to God and to our fellow man. Many relationships have collapsed because of unfaithfulness. For love to abound in our interpersonal relationship, much of it hinges on being faithful to each other. When people are hard-pressed, they tend to compromise and sell out their faithful attitude. This may tear down relationships and lead to serious conflicts in interpersonal relationships.
Luke 16:12 explains the need for faithfulness in our finances. There are folks who are cheating on less-privileged ones for their money just because they may need employment, travel, or health attention. Some people collect money from friends and never pay it back, putting them in a state of jeopardy. We have been advised in Colossians 3:9 that we do not have to lie to one another. Our faithfulness in our vertical relationship with God must have a completely positive relation in our horizontal relationship with fellow men.
