You have given a banner to those who fear You, that it may be displayed because of the truth. (Psalm 60:4, NKJV)
For centuries, armies used banners or flags to identify and distinguish themselves from their enemy on the battlefield. The raised banner was a rally point for combat, giving assurance that the cause was advancing on the field of battle. God has raised the banner of His Christ as the rallying point for salvation from sin, and as our signal to advance against the enemy, the devil (Isa. 11:10; Rom. 15:12). The cause of truth is identified by, and advances under, God’s banner. It does not fly for the sake of “vain parade or ostentation; it was not to be unfolded in an unrighteous or unjust cause” (Barnes on Psa. 60:4). The banner of the cross is unfurled by all who fear God and work righteousness (Acts 10:34-35). The cause of divine truth will be victorious. Christians, who march according to the authority of Jesus Christ, advance to victory (1 John 5:4; Rev. 17:14).
