Ephesians 6:10: “Finally, be strong in the Lord and in his mighty power.”
Apostle Paul encourages us to be strong. But how? Do we have to be strong in ourselves with our own human strength? No, he says that we have to be strong in Him. How do we do that? By being in his mighty power. How is that possible? His word is full of his power. You stay in His word and you stay in his power. These two are synonyms. Of course, if you read the word casually and do not pay attention to the real meaning behind the words you will probably not experience that strength. However, if you meditate on what you have read you will know that power.
