At times, believers tend to get at odds with other believers. Instead, we should be thankful for our fellow believers and the benefits they bring to the body.
Strength is not tested or demonstrated during times of ease. Rather, it is during times of adversity that one finds out just how strong he is.
Sin causes a man's strength to fail. On the contrary, "the way of the LORD is strength to the upright." Man's choice to sin will eradicate his strength.
Sin affects men in various ways, but it attacks them in every facet of life. It hinders their walk with God and hurts their ability to reach others for Christ.
People in the world are generally quite self-centered. Even saved people are often lovers of their own selves instead of preferring one another.
