By all means, do pray for Paris. Do pray for the victims and their families. But don’t stop there. Pray for Europe and the Americas. Pray for Asia, Africa, and Australia. Pray for freedom-loving people everywhere, but more importantly “pray the Lord of the harvest to send out laborers into His harvest. Go your way; behold, I send you out as lambs among wolves.” (Luke 10:2b-3).
“And from the days of John the Baptist until now the kingdom of heaven suffers violence, and the violent take it by force.” (Matthew 11:12). The kingdom of heaven will continue to suffer violence, and those who seek it will need to fight harder and longer to obtain it with every passing day.
Even so, the primary weapon is not military might. “For though we walk in the flesh, we do not war according to the flesh. For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, 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, and being ready to punish all disobedience when your obedience is fulfilled.” (2 Corinthians 10:3-6)
So put on the full armour of God as described in Ephesians 6:10-17, but don’t stop after merely suiting up. Go on and fight: “praying always with all prayer and supplication in the Spirit, being watchful to this end with all perseverance and supplication for all the saints—and for me, that utterance may be given to me, that I may open my mouth boldly to make known the mystery of the gospel, for which I am an ambassador in chains; that in it I may speak boldly, as I ought to speak.” (Ephesians 6:18-20)
