In Galatians 5:22-23, love is translated from the Greek word ἀγάπη, (agape). Greek has multiple words for love including eros, which is sexual love and philos, which is brotherly love. Agape’ is perfect love that only God can give.
“In respect of agapao as used of God, it expresses the deep and constant ‘love’ and interest of a perfect Being towards entirely unworthy objects, producing and fostering a reverential ‘love’ in them towards the Giver, and a practical 'love’ towards those who are partakers of the same, and a desire to help others to seek the Giver,” according to Vine’s Expository Dictionary.
Love for God and others is the result of receiving God’s perfect agape’ love. Jesus encouraged his followers:
“As the Father has loved me, so have I loved you. Now remain in my love. If you keep my commands, you will remain in my love, just as I have kept my Father’s commands and remain in his love. I have told you this so that my joy may be in you and that your joy may be complete.” (John 15:9-11).
