We find it easier to recognise someone and understand their behaviour when we know them well. This same principle applies to our relationship with God. The more substantial our knowledge of him, the more able we are to work out what he wants us to do. This is one of the reasons that Bible study and meditation is such a vital part of every Christian's journey to spiritual maturity. To truly determine whether or not something you feel you're called to do is part of God's plan or not, you'll need to study his character in the way it is presented in the Bible. In the meantime, the following Bible verses all provide some insight into the nature of God's will in terms of how it is relayed, what it refers to and how it is carried out.
