There's no greater danger to one's personal peace and joy than conflict. Anger, arguments, disagreements, and all sorts of issues cause untold stress in our lives. Fortunately, the Bible has a way out of all that and the core of it starts with our own ultimate commitment. We aren't to rely on our own understanding (Proverbs 2:5-6) but base our reasoning on the principles of Scripture. Sadly, this is a rare thing...even within the church! Next, we're to focus on Christ and follow Him while, importantly, granting that same right to other Christians (John 21:22).
Conflict comes from only one source: the denial of the authority of the Word of the Lord in our lives. To live peaceably with everyone, so long as it depends on us, we must endeavor to be transformed in our thinking so that all facts and circumstances are evaluated through biblical principles. When we do that, our conflicts will be less and less.
