Commenting on I John 4:19, which reads “We love him, because he first loved us,” John Wesley wrote “This is the sum of all religion, the genuine model of Christianity. None can say more: why should any say less...” (Explanatory Notes on the New Testament) This love God has for us is most fully revealed in the cross of Jesus Christ.
In his sermon “God’s Love to Fallen Man,” written in the last decade of his life, Wesley raises a common question: Why did God allow humanity to fall into sin? His answer was that for God to permit the fall would produce “abundantly more good than evil,” enabling persons to be “more holy and happy” both on earth and heaven.
