Why should Christians avoid strife and vainglory?

In Philippians 2:3, Paul explicitly warns against allowing strife and vain glory to influence our hearts and actions. These attitudes usually stem from a focus on self rather than God or others, which hinders our relationship with Him and damages the Church's unity. Strife leads to division, while vainglory promotes a false sense of superiority that is detrimental to spiritual growth. By actively choosing to follow Paul's instructions and fostering a spirit of humility and love, Christians can create a nurturing environment that reflects the character of Christ and draws others to Him.
