Ephesians 6:10 "Finally, my brethern, be strong in the Lord, and in the power of His might". Paul, exhorting the brethern, in which we are because we are in Christ, tells us to be strong in the Lord. What does it mean to be strong in the Lord? Does it mean to be a good person? Or attend church regularly? Does it mean to volunteer or help the poor and needy? There is nothing wrong with those things. But Paul isn't talking about just doing acts of kindness. He is telling us it imperative that we be strong in our walk and relationship with God. So that we can stand strong during difficult times and have victory, not only for ourselves; but for those we love and care about, including the world.
The world? You might ask, yes the world. Because God loves the world. He sent His Son Jesus to save the world (John 3:16). Peter wrote that the Lord is not willing that any should perish, but that all should come to repentance (2 Peter 3:9). So you see, being strong not only helps us to overcome, it helps those in the world to understand what they need to do to walk in victory.
In Ephesians 6:13, Paul tells us to take the whole armor of God that we may be able to withstand in the evil day. If there were ever an evil day, it is these days we live in now. If the church and true believers are not able to withstand, how will the world? Believers need to be strong in the Lord. We need to walk in victory so that we can be an example to the world. We need to let them see that in Christ they can overcome in the evil days we live in. Paul continues to write in verse 13 "and having done all to stand". Have we done all to stand in this evil day. Have we studied to show ourselves approved unto God? A workman that needeth not to be ashamed, rightly dividing the Word of Truth (2 Timothy 2:15). Have we prayed without ceasing? (1 Thessalonians 5:18) Have we been transformed by the renewing of our mind that we may prove what is that good, acceptable, and perfect will of God? (Romans 12:2) If we have done all to stand, then we need to do as Ephesians 6:14 says and stand therefore. If not, we need to get to the business of having done all to stand!
