How does believing in God fill us with joy and peace?

In Romans 15:13, Paul emphasizes that it is through believing in the God of hope that believers experience an abundance of joy and peace. This filling is not a passive occurrence; rather, it is an active process facilitated by the Holy Spirit, who works within us to produce evidences of faith. As we understand the truths of the gospel and our identity in Christ, we are filled with joy that arises from gratitude and peace that comes from being reconciled to our Creator. Thus, faith is the channel through which God's blessings of joy and peace flow into our lives, reflecting His character and promises.
