Psalm 92:10 NKJV
But my horn You have exalted like a wild ox; I have been anointed with fresh oil.
The psalmist speaks about how he was anointed with fresh oil. The anointing is in us but it needs to be refreshed constantly. The apostle Paul told Timothy to stir up the gift inside of him (2 Timothy 1:6). It was in Timothy, but without a refreshing of it - a stirring, the gift would not remain active and productive. Paul told the Ephesian church to be filled with the Spirit (Ephesians 5:18). They were a spirit-filled church, but the apostle was encouraging them to keep it fresh. We need fresh oil - a fresh anointing, fresh fellowship with the Holy Spirit each day. How did Paul say they could do this?
Ephesians 5:19-20 NKJV
speaking to one another in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord, [20] giving thanks always for all things to God the Father in the name of our Lord Jesus Christ,
