Indeed, it is only through trusting Jesus that we can understand God's plan for us and carry out his will in our daily lives. Yes, John 'the beloved disciple' of Jesus has given us a powerfully spiritual portrait of our Lord and Master, the Eternal Son of God. He knew that love, and he wants his readers across the ages to know it too. Love, as John sees it, is not an invitation to indulge in a life of indiscriminate sentimentality or superficial spirituality. Second, God has forgiven us because his only begotten Son died in our place.
Genuine repentance acknowledges both the sentence and the acquittal.
In response, John tells us that God demands nothing less than our wholehearted allegiance. God's calling is too important to be trivialized. You can read the 21 chapters of John in a couple of hours. The gospel is perfect reading for new Christians, but it also repays the study of a lifetime. It has changed millions of people.
