The Lord is a jealous and avenging God.Nahum 1:2
Believer, your Lord is very jealous of your love. Did He choose you? He cannot bear that you should choose another. Did He buy you with His own blood? He cannot endure that you should think you are your own or that you belong to this world. He loved you with such a love that He would not remain in heaven without you; He would sooner die than have you perish, and He cannot endure that anything should stand between your heart's love and Himself.
He is very jealous of your trust. He will not permit you to trust in yourself. He cannot stand the thought of you hewing out broken cisterns and neglecting the overflowing fountain that is always free to you. When we lean upon Him, He is glad; but when we transfer our dependence to another, when we rely upon our own wisdom or the wisdom of a friend-worst of all, when we trust in any works of our own-He is displeased and will chasten us, that He may bring us to Himself.
He is also very jealous of our company. There should be no one with whom we converse so much as with Jesus. To remain in Him alone, this is true love; but to commune with the world, to find sufficient satisfaction in our earthly comforts, to even prefer the company of our fellow Christians to secret fellowship with Him, this grieves our jealous Lord. He longs to have us abide in Him and enjoy constant fellowship with Himself; and many of the trials that He sends us are for the purpose of weaning our hearts from created things and fixing them more closely on Him who created everything. Let this jealousy that would keep us near to Christ also be a comfort to us, for if He loves us so much as to care about our love, we may be sure that He will allow nothing to harm us and will protect us from all our enemies. May we have grace today to keep our hearts in holy purity for Christ alone, with sacred jealousy closing our eyes to all the fascinations of the world!
