When you read the account of Stephen in Acts 7 and see the strength of his character in active faith and the use of Scripture to display the wisdom of God, it is undeniable that the Holy Spirit filled him to powerfully proclaim truth. Though Saul was on the wrong side of truth at this point in his life, the event left its mark on his heart.
Who has lived Christ before your eyes in a way that you cannot forget? What change has this produced in you so your life can be the same witness to others? As Paul became a living example of Christ to persons like Silas, Timothy, Titus and others, you and I need to continually and purposely live for drawing other to Christ through our character.
