Matthew 13:25

Matthew 13:25. But while men slept, his enemy came and sowed tares among the wheat, and went his way.

Wherever Christ is active the enemy is sure to be active too. If you have a sleeping church, you may have a sleeping devil; but as soon as ever Christ is in the congregation sowing the good seed, the devil wakes up, and by night, when men are off their guard, the bad seed - the mock wheat -here translated "tares" - is sown among the true wheat.
