What does the Bible say about the oneness of the Father and the Son?

The oneness between the Father and the Son is a central theme in scriptures, particularly evident in John 14:10 where Jesus asks, 'Believest thou not that I am in the Father, and the Father in me?' This profound unity signifies that in Christ, the fullness of the Godhead dwells, affirming His divine nature and redemptive work. When we contemplate this union, it assures us that every grace, mercy, and blessing flows from this relationship.

Specifically, God was in Christ, engaging in the redemptive work for humanity, thus manifesting God’s essence through Christ's life and actions. The fullness of grace and glory in Jesus guarantees His people a complete supply of spiritual blessings. As believers, the realization that we have Christ means that we also have the Father, making this relationship vital to our faith and understanding of God's redemptive plan.
