What is Paul asking us as Christians in Philippians : 2 1-4 when he asks us to be “united in heart, thinking one thing” as we act humbly for the betterment of others? The Spirit links our hearts in a very emotional way, filling them with faith and love. Surely Paul was aware that the power of so many hearts filled with so much faith and acting in selflessness could create culture-shifting movements within societies rooted in stagnant belief systems and stale religious practices like the ones ringing the Mediterranean world at that time. But that awesome power for change had to be directed “by being of the same mind” in order to achieve the good ends that were sought.
