We have far too light a view of sin. You and I do not realize what sin is or what consequences come with it. We fail to see it because we have it - sin prevents us from seeing God for who He is, and a failure to see God for who He is is a failure to see sin for what it is. Even as I type these words, the concept that even one of my hundreds and thousands of daily sinful deeds is deserving of an eternity separated from the love of God is as foreign to me as Mandarin. It is a concept I cannot grasp.
God did not save us so that we would live passively - He saved us to be holy. This is our ultimately and impossible task because God's holiness by definition means that we are not like Him; we can't be. That is why our holiness is completely dependent on His grace.
Lately I have come - again - to the realization that I cannot resist sin and live in holiness without His Spirit and His word. The more I dig into the Bible, the more I see my need for it.
And the more I see my need for it, the more I love Him.
