Jesus calls on us to have faith and repent. He explains that the Kingdom of God is near. The Kingdom is here in the form of the Holy Spirit. Just as the Holy Spirit is seen descending from Heaven to land on the earthly Jesus at His Baptism, so we all receive the gift of the Holy Spirit at our Baptism. God through the Holy Spirit, wants to guide our lives and be in a relationship of holy love. Since the Holy Spirit cannot bear to be around the un-holy, we must repent and seek forgiveness to be in a relationship of holy love with the divine.
1. The challenge of a holy love relationship
God had a challenge when He created us. Love is a choice. In order for us to be able to chose to love God, God had to give us free will and the possibility of not choosing to love Him. The point is that God loves us so much, and wants a holy love relationship with each of us so much that He decided to take a huge risk.
