It's kind of a package deal. Separation from God is something we should avoid at all costs-but we're born in that separated, fallen condition. And one of the first reactions to knowing God is awe, and, yes, fear of His power, of life over death. But as we come to truly know Him through His Son, we find, over time, that He's gentle and kind and loves man lavishly, and has always wanted the best for him, and He knows that the best for us begins with Him. And that's where faith comes in, that's how we get with Him.
But we're like prodigals or wild things, in rebellion, filled with pride, not necessarily sure we want to come completely in from the wild, needing to be convinced, which is a primary purpose of the Cross to begin with, which stands ever-beckoning us to come -and come even closer to that light, to that love. Anyway, the nearer we draw to God the nearer He draws to us and the more we know Him the more our faith, hope, and love grow. And fear is cast out, overcome, by that love- 1 John 4:18. And that love simultaneously overcomes sin, because, again, the two are mutually exclusive. I'll repeat Basil one more time, which shows a progression.
If we turn away from evil out of fear of punishment, we are in the position of slaves. If we pursue the enticement of wages, . . . we resemble mercenaries. Finally if we obey for the sake of the good itself and out of love for him who commands . . . we are in the position of children.
