Don't be drunk with wine, because that will ruin your life. Instead, be filled with the Holy Spirit. - Ephesians 5:18
In the Christian life we often try in our own strength to do what God has called us to do. We think, I've got to keep God's commandments and resist temptation and love my spouse and. . . . It is hard stuff.
But when we say, "Lord I can't do this on my own. I just ask that your Holy Spirit would fill me and help me to do these things," we will realize that doing what God tells us to do can actually become a delight rather than mere duty.
The Bible says, "Don't be drunk with wine, because that will ruin your life. Instead, be filled with the Holy Spirit" (Ephesians 5:18). The word "filled" used here carries multiple meanings, one of which is wind filling a sail. So to be filled with the Spirit means being carried along by, and under the control of, Jesus Christ. The word "filled" in this verse also speaks of something that is continuous. So effectively, this verse is saying, "Be filled over and over and over and over again with the Holy Spirit."
Another way the word "filled" could be translated is "to permeate," the way salt was packed into meat to preserve it. So to "be filled with the Holy Spirit," means that we need to let the Holy Spirit permeate our lives and everything we do. Let the Holy Spirit permeate your prayer life, your worship life, your business, your marriage, and the way you treat others.
So a good habit to develop is to get up in the morning and say, "Lord, fill me with the Spirit today. Help me to be permeated by the Spirit. Help me to be led by the Spirit. Help me to obey what the Spirit leads me to do."
