John MacArthur said, “God’s own love is the inexhaustible well from which, as it were, we can draw the supernatural love He commands to live by.”
As a Christian, the love of God has been poured out within your heart (see Romans 5:5). The moment you received Christ for the forgiveness of your sins, the Holy Spirit came to live in you and He poured out the love of God into you. You see, you don’t have to pray for God to give you more love for someone. What you should pray for is for God’s help in letting it out. The love of God is in you, you just need to let it out. This is how you pay the debt of love.
