In conclusion, be strong in the Lord [be empowered through your union with Him]; draw your strength from Him [that strength which His boundless might provides].
In the Lord is where a believer can find all the strength they need, the strength to face and overcome any challenge in life. It didn’t say be strong in yourself, but in the Lord. In Ephesians 6 it goes on to tell us to put on the whole armor of God so we can be strong and stand against our enemy. It begins with the belt of truth. Equip yourself with the truth of God’s Word by living in the Bible and applying what you learn.
Next put on the breastplate of righteousness, living a life of integrity, listening to your heart and obeying your conscience (the voice of your spirit man). Walk in the gospel of peace. Jesus brought good news of how we can have peace with God by being restored in our relationship with Him. Walk with Him daily, focused on Him and you walk in peace. Take up the shield of faith by continually hearing the Word preached with a reverence and a hunger for God.
Next use the helmet of salvation by keeping your thoughts in line with the Word of God, casting down every thought that is contrary to God’s Word. Finally take the sword of the Spirit, which is speaking God’s Word, especially when circumstances come against you. Declare what God has said and therefore use your sword to change those circumstances. We have been given all we need to be strong in the Lord. It is up to us to live in the armor we have been given.
