Most people already know more than they need to know...it is simply LIVING what we claim we know that needs to be done. We don’t become doers on our own, as we read the Scripture, we ask the Spirit to help us understand what to do in response. The intersection of what the Scriptures teach and how our lives unfold will give us a never-ceasing stream to actually do what Jesus says.
God created you to simply be you, not anyone else on the planet (or in all of creation). Unfortunately we all seem to think we need to be someone else in order to truly grow into who we think God wants us to be... but only GOD knows who he wants us to be.
