“And if Satan is divided against himself, how will his kingdom stand?” (Luke 11:18) Satan understands the strength of unity. “Evil measures higher than good” is indeed a wise proverb. However, those who follow Jesus know that “unity” is the desire of Jesus (“Father! May all of them be one.”), but they are still walking in the opposite direction. Jesus said with emotion, “For the children of this world are more prudent in dealing with their own generation than are the children of light.” (Luke 16:8) “Unity” is the connotation of the life of Holy Trinity. The Father loves the Son while the Son reciprocates his love to the Father (by practicing His will). This mutual love is the Holy Spirit. Holy Trinity is essentially the relationship of mutual love. When mankind is “divided against himself ”, “love” will be expelled from the door. “Satan” is rejected to enter the heavenly door for he is lacking love. However by knowing the way to make humans to “attack one another” it drives them away from the Heaven’s Gate. So, when mankind is divided, we could easily become even worse than “Satan”! “And if Satan is divided against himself, how will his kingdom stand?” Lord, please forgive our sins for lacking love to one another.
