To be filled with the Holy Spirit means the word of Christ dwells in us richly. It means that we are abiding in Christ and in His word. We cannot separate Christ from the Holy Spirit as we cannot separate the Holy Spirit from Scripture.
God’s commandments are for our good and His glory. God, through Paul, issues a command to His beloved children to be filled with the Spirit. We must understand this is not an option or an add-on for the Christian. We must be filled with the Holy Spirit. We cannot live the Christian life apart from it.
We have an innate desire to want to be loved. The Apostle John reminds us in this passage that we have been loved by God and God placed us in His family to be loved. We are doubly loved. We are loved by God and loved by our brothers and sisters in Christ. God has placed His children in a loving family, a family that loves because God loves them. I don’t know about you but that is something I want to be a part of.
We were darkness but now we are light in the Lord (5:8). The text does not say we were in darkness but rather we were darkness. Our lives were characterized by sin and ignorance of God’s truth. But that is not who we are now. Now we are light. We are holiness and we have been given knowledge of God’s truth.
