2 Corinthians 5:14 For the love of Christ constraineth us; because we thus judge, that if one died for all, then were all dead:

It is Christ’s love that is imparted to us giving us the capacity to love others. The Apostle Paul himself was a blasphemer. He persecuted Christians. Indeed, if Christ has not had compassion on him, he would have perished eternally. He was turned around by the blinding that came to Him when Jesus met him on the road to Damascus. He was subsequently healed of his blindness. He was grateful for being connected with His Creator and Sustainer and Saviour. He experienced the peace, love and joy of God imparted to his heart. He testified in Romans 5:1-2, 5b-8, 11 Therefore being justified by faith, we have peace with God through our Lord Jesus Christ: By whom also we have access by faith into this grace wherein we stand, and rejoice in hope of the glory of God… because the love of God is shed abroad in our hearts by the Holy Ghost which is given unto us. For when we were yet without strength, in due time Christ died for the ungodly. For scarcely for a righteous man will one die: yet peradventure for a good man some would even dare to die. But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us… And not only so, but we also joy in God through our Lord Jesus Christ, by whom we have now received the atonement.
