The topic of 'Trusting in God' is central to both of the podcast episodes provided, as they encourage listeners to rely on God's guidance and power to handle difficult situations and people.

In the first episode, Joel Osteen encourages listeners to trust in God to handle their battles with difficult people, letting God fight for them instead of trying to handle it themselves. This ties into the broader themes of character, integrity, and maintaining peace and joy even in the face of adversity.

The second episode, from 'The Bible in a Year' podcast, concludes with a reflection on Psalm 62, which emphasizes the importance of trusting in God alone as the source of salvation and steadfast love. This episode also discusses the role of parental example and advice, and how the Old Testament can foreshadow themes in the New Testament, such as the role of the queen mother and its connection to the role of Mary.
