Psalm 89:15-16 describes the blessed. It says:
Blessed are the people who know the festal shout,
who walk, O LORD, in the light of your face,
who exult in your name all the day
and in your righteousness are exalted.
Here are 4 things that describe those who know the Lord. First, they worship. The festal shout is given in worship. God called us to Christ because he sought worshippers. (John 4:23) Second, they walk with the Lord in constant fellowship. That is true of us especially as we have the Holy Spirit dwelling in us. (Romans 8) Third, they exult or rejoice in the fact that they know God (his name) all day, despite whatever trials may come. (Philippians 4:4) Fourth, their salvation comes not from their own works, but from Christ's righteousness. (Ephesians 2:8-9)
Maybe you could get in a festal shout today.
