If our conversion, our turning, is basically understood to be something we do ourselves instead of being something God does in us, then we misunderstand it. Conversion certainly includes our own actions. We must make a sincere commitment. We must make a self-conscious decision. Even so, conversion – real conversion – is more than that. Scripture is clear in teaching that we are not all journeying toward God – some having found Him, others still seeking. Instead, Scripture presents us as needing to have our hearts replaced, our minds transformed, our spirits given life. We can do none of this for ourselves. The change each human needs, regardless of how we may outwardly appear, is so radical, so near our roots, that only God can bring it about. We need God to convert us.
