Unity promotes oneness. It is one vital characteristic that everybody must cultivate. Jesus desires for His disciples to be one. His prayer to His Father the night, before He was crucified, was a prayer of unity for all believers. Oneness cements the body of Christ together. Without this sense of oneness, we disintegrate, devour one another and finally lose out on God's agenda for our lives. Lack of oneness is a sure way of trouble in our relationship with one another. The best way we can build oneness is to be in spiritual harmony and agreement with each other!
Discouragement is a temptation “common to man” – “There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it.” (1 Corinthians 10:13). – And in dealing with it, sometimes we need tenderness and other times we need toughness. But either way, discouragement is not to be tolerated or wallowed in. It is to be fought!
