Why is it important to avoid strife among Christians?

Strife among believers is not only detrimental to relationships but also tarnishes the witness of the Gospel. Abraham's admonition to Lot, 'Let there be no strife, I pray thee, between me and thee, for we be brethren,' emphasizes the unity expected among believers. Ephesians 4:3 urges us to endeavor to keep the unity of the Spirit in the bond of peace. By avoiding strife, believers demonstrate humility, love, and the character of Christ, thereby manifesting the truth of the Gospel to the world around them.
