Beloved ones of Christ, we are to always be ready to defend our faith. I have seen some when doing this, be stiff-neck in their response. But Christ wants us to speak with love in a gentle way. Satan wants us to become angry, in order to stain our testimony. We might not be able to change the person’s mind who is attacking our faith, but if others are looking on, might see Christ within us. Hopefully, you had your prayer time earlier and faced this person with Christ. The way we respond to others speaks clearly of God’s love. Also, one must know when to walk away.
Read I Peter 3:16
