Our real connection to Jesus Christ must always lead to our true connection to one another. Division points to a brokenness in some aspect of our relationship with God.
Division in our hearts or in our relationships is a signpost pointing to a break in our connection to our Heavenly Father. But He is always standing by with His door open for our return and ready to receive us into His presence. We must be prepared then to leave our own doors open for restored relationships to those around us. An open door means no demands or expectations but rather a reflection of the grace by which Jesus Himself has accepted us.
