[Andrew] first found his own brother Simon, and said to him, “We have found the Messiah.” John 1:41
As believers in Christ, we have a much more significant invitation to extend: We have received a new life of faith in Jesus and want others to experience it too. Some will want to do so, and others won’t. In John 1:40 we read that Andrew had begun to follow Jesus. The first thing Andrew did was to find his brother Simon and invite him to meet Jesus, the Messiah, too (v.41). Jesus offered them a wonderful new way of life of knowing Him and enjoying His promises: His forgiveness (Rom. 3:24), continual presence (Heb. 13:5), hope (Rom. 15:13), peace (John 14:27), and a forever future in His presence (1 Thess. 4:17).
Jesus gives the best life.
If you want someone to know what Christ will do for him, let him see what Christ has done for you.
