Ephesians 4: 26 Be angry, and sin not: let not the sun go down upon your wrath. 27 Neither give place to the devil.
The issue of giving another person the benefit of the doubt will cause us to put the very best construction upon the words and actions of others. No, the person did not mean to disregard, or evade your call. They were actually on the other line with an emergency call from their doctor, who had given them some bad news about a diagnosis of cancer, and because of the grave nature of the conversation they had really forgotten to call back.
It all has to do with giving persons the benefit of the doubt, and not becoming riled up or easily provoked if, and when things do not go according to script. In our interaction with other folks, and in our efforts to seek and cultivate peace and good will, there would be instances when we might have to bite the bullet, and let things slide, leaving the situation with God.
In other situations, if persons speak or approach us in derogatory or intimidating ways, instead of going the route of self-preservation, we will have to keep our cool, and maintain a Christlike demeanor, even in argumentative situations. Sorry to say it, but some Christian spouses have the habit of arguing with one another, and in some cases, some are always on edge so that the least ruffling of their feathers, triggers a flurry of un-Christlike words and actions. This is what the Bible has to say in such situations.
Ephesians 4: 29 Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers. 30 And grieve not the holy Spirit of God, whereby you are sealed unto the day of redemption. 31 Let all bitterness, and wrath, and anger, and clamor, and evil speaking, be put away from you, with all malice.
May God add His blessing to the study of His word. “Good night” and God bless!
