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).
3 For though we walk in the flesh, we do not war according to the flesh. 4 For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, 5 casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ, 6 and being ready to punish all disobedience when your obedience is fulfilled. (2 Corinthians 10:3-6)
Christians are at war, and we’d better realize it! The battle is raging for the minds and souls of every person on earth, including ours. Guns, tanks, missiles and bombs will not defeat our enemy. We wage a spiritual warfare, “the good fight of faith” (1 Tim. 6:12). Our weapons are spiritual in nature and “mighty in God” to break down the bulwarks of unbelief, human wisdom and pride. The “sword of the Spirit”, the word of God, renders error impotent. Truth vanquishes every foe and as it leads us to obedience and victory in Christ. The question is not whether Christ and His army will prevail. The question is, in which army are you a soldier; Satan’s or the Lord’s?
