What did Jesus teach about God and the living?

In Jesus’ teaching to the Sadducees, He made it clear that God identifies as the 'God of Abraham, Isaac, and Jacob,' even though these patriarchs had been dead for centuries. This declaration signifies that they are alive to God, indicating an eternal existence beyond physical death. Jesus emphasizes that those who are in Him possess eternal life, a life that transcends mortality and is characterized by a relationship with the living God. This perspective provides believers with assurance of life after death and the continuous presence of God in their lives, portraying the victorious nature of God’s promise of resurrection.
