Read Luke 8:16-18

ILLUSTRATION OF THE LAMP
When the light of the truth about Jesus illuminates you, it is your duty to shine that light to help others. Your witness for Christ should be public, not hidden. You should not keep the benefits for yourself alone, but pass them on for others. In order to be helpful, you need to be well placed. Seek opportunities to be there when unbelievers need help.
Applying God’s Word helps us grow. This is a principle of growth in physical, mental, and spiritual life. For example, a muscle, when exercised, will grow stronger, but an unused muscle will grow weak and flabby. If you are not growing stronger, you are growing weaker; it is impossible for you to stand still. How are you using what God has taught you?
