For Individuals
One can read in his or her own time and use the questions as an opportunity to think on what is written, a bit like in the Book of Psalms where the writer adds the word selah (71 times in Psalms). Selah means to pause and meditate or think upon what has just been written.
Writing your thoughts about the questions in a journal can reveal more information than just thinking through the questions. Writing can help you to explore a little deeper than just the surface level. The studies in Luke are written in a commentary style that is more conversational than scholarly.
