How do we know the promise of the Spirit is true?

The promise of the Spirit is a profound assurance given to believers who trust in Christ. According to Galatians 3:14, the blessing of Abraham is closely tied to receiving the promise of the Spirit through faith. This shows that the Spirit's indwelling is a result of faith in Christ's redemptive work. Paul highlights that God has justified those who believe in Jesus, assuring them of their inheritance and the gift of the Spirit. The Spirit acts as a down payment of this promise, affirming our identity as children of God and our position in His family.
