I Tim. 1:4 Don't let people waste time in endless speculation over myths and spiritual pedigrees. For these things only cause arguments, they don't help people live a life of faith in God.
How much time is wasted over arguing over things that really don't matter? Probably a lot. We sometimes get into some interesting "discussions" that end up doing nothing more than cause hard feelings that sometimes results in broken fellowship that is never quite restored. How sad!! We need to be careful about what issues we choose to get defensive over. As much as we would like to think otherwise, our opinions really don't matter all that much. What does matter are those things which help us and others to grow in faith.
We need to focus our attention on things that edify the soul and the source of those things is the Word of God. The Word of God should never be argued over. We can have different understandings on interpretations and applications, but they should NEVER be allowed to sever relationships in the body of Christ. We should agree to disagree agreeably on our different understandings and move on to how we can help each other grow in faith.
If we truly love each other as God loves us, we will work very hard to live peaceably with each other and work together for our common good and Christ's glory on earth. Loving each other ought to disarm those things which divide us. As long as Christ is the focus of our faith and we rally around the cross, we should accept one another as brothers and sisters in Him and help each other become a holy people, a people after God's own heart.
