The direction of our lives is shaped by the decisions that we make. The most important decision is to follow the Lord Jesus Christ within the fellowship of His Church. The Lord Jesus Christ is the Master of our lives and the Model for living. In the Gospel reading (cf. Mark 8:27-35), the Lord Jesus teaches that it is possible to practice the faith that we profess in response to His revelation. After the first prediction of His passion, death, and resurrection, Peter the Apostle thought that Jesus was talking nonsense. The Lord taught Peter to have some sense and become a decisive disciple. We should not be discouraged if we have sinned. To live a decisive Christian life is possible as we undergo conversion, deal with circumstances, and endure conflict as we live according to the values of Christ.
