Oh what can be done with an old heart like mine?  Soften it up with Your oil and wine.  This song by Keith Green goes on to explain that the oil represents God’s Holy Spirit and the wine His blood…To prevent out hearts from hardening, we must stay surrendered to Jesus Christ.  Such victory will require drawing near to Him, spending time with Him, abiding in Him, receiving His “oil and wine.”  Then, and only then, can we experience the love of God melting the hardness of our stubborn hearts.  This is the only way to make it in this heart-hardening, soul-destroying world.
