Ephesians 5:18-20

Do not get drunk on wine, which leads to debauchery. Instead, be filled with the Spirit. Speak to one another with psalms, hymns and spiritual songs. Sing and make music in your heart to the Lord,

(v18-19, NIV)

Paul instructs us to be filled with the Spirit. The question is, how are you to be filled with the Spirit? Well, Paul answers that question. First, we are to speak to one another with psalms, hymns and spiritual songs. As Paul stated earlier, we aren't to have coarse joking or foolish talk. Instead, we should say things that are wholesome and worthwhile. Psalms, hymns and spiritual songs are worthy things to be said. We are also to worship God. Worshipers are probably ones who are filled with the Spirit.

always giving thanks to God the Father for everything, in the name of our Lord Jesus Christ.

(v20, NIV)

Another important thing to being filled with the Spirit is thankfulness. We are to give thanks to God for everything. Thanksgiving and thankfulness should proceed out of our mouths and out of our hearts. We can thank with our mouths and not with our hearts. Instead, we should be truly thankful, which may include thanksgiving with our mouths.
