The Spirit of Christ is the Spirit of Missions, and he nearer we get to Him the more intensely missionary we must become.  Henry Martyn

It is well said that “asking is the rule of the kingdom.” It is a rule that will never be altered in anybody’s case. If the royal and divine Son of God cannot be exempted from the rule of asking that He may have, you and I cannot expect to the rule  relaxed in our favour. C.H. Spurgeon

Here lies the supreme missionary motivation. It is neither obedience to the great commission, nor compassion for the lost, nor excitement over the gospel, but zeal (even ‘jealousy’) for the honour of Christ’s name…no incentive is stronger than the longing that Christ should be given the honour that is due to His Name. John Stott
