But that which ye have already hold fast till I come.
Firstly, it’s not enough to reject satanic lies; we must also hold fast to the truth we’ve received. Good Christians are not blown about by every wind of doctrine, the sleight of men and cunning craftiness (Ep 4:14). Don’t let anything loosen your grip on the truth you’ve grasped. Secondly, the deadline of our endurance is defined as unto the PAROUSIA. It’s not enough to follow the truth for a long time and then give up before Jesus returns. Beloved, let us serve the Lord with the right deadline in mind. Forget about 5-year plans. Forget about 20-year plans. Think eternity!
