How sad it feels when we share an environment where for some reason, people with different characters exist and collide with each other.

God loves unity and reminds us that we must remain in harmony, that is, that we all have to do our part not to create a conflictive environment. Certainly the natural man finds it difficult to follow this command since they do not have God in their lives.
But we who, if we know God, must express unity.

4 a body and a Spirit, as you were also called in the same hope of your vocation; 5 one Lord, one faith, one baptism, 6 one God and Father of all, who is over all, and through all, and in all.
Ephesians 4: 4-6 King James Version (RVR1960)

Harmony between brothers makes us one, therefore we must strive more to seek unity on all sides to please God, and he will bless us.
