So often we don’t believe that God will or actually can speak to us at all, let alone about such a tremendously subjective matter as our own hidden agendas. However, there have been many times when I’ve asked God to make clear to me what was going on behind my behaviors, and then later I’ve been reading along in Scripture or writing my thoughts in a journal and knew God was clearly giving me insight. Also, there are a number of Bible studies available that ask provocative questions which facilitate hearing from God about whether what you believe lines up with Scripture. (For example, see the NavPress “Life Changes” series or Tyndale House Publishers’ “Life Application® Bible Studies.”) God also communicates through his Body, the church. When we stay in active fellowship with Christians who care about growing in faith, God uses interaction with fellow believers to reveal to us where we’re off base in our thinking.
If you believe God has not been revealing to you the beliefs and thoughts that are motivating your overeating, start to very regularly read the Bible while asking God to show you personal application. The Bible says of itself that it is “living and active” and “judges the thoughts and attitudes of the heart” (Hebrews 4:12). Also, God has declared that his Word will always have an effect on those who are exposed to it (Isaiah 55:11; John 17:17). Through exposure to Scripture, even if you do not “hear” God speaking specifically to you about the beliefs that motivate your overeating, your beliefs will be changed.
The Holy Spirit is more interested in revealing to us the truth about ourselves than we are in hearing it. When we are willing to hear from God, he speaks in a variety of ways to the issues of most concern to him and to us.
