Are you seeking quality materials to guide your meditations on “whatever is true”? I found the following books personally beneficial, though not infallible. First, there are two books on truth itself. Specifically, why it’s become so hard (even among Evangelicals) for people to affirm it:
The Courage to Be Protestant: Truth-lovers, Marketers, and Emergents in the Postmodern World by David F. Wells
This book summarizes and re-casts the key lessons of Well’s four prior books, based on decades of research and analysis of Scripture, history, and culture. Read Tim Challies review and I think you’ll want to tackle it.

No Place for Truth, Or Whatever Happened to Evangelical Theology by David F. Wallace
This is a somewhat dense book. Yet in my estimation, three decades after it was written, it remains one of the best accounts of how the Western church has largely come to adopt a post-modern mindset, often without even realizing it. Essential reading for anyone who wishes to understand the present moment.

Next, several excellent books which help guide your meditation upon Jesus Christ:
Rejoicing in Christ by Michael Reeves
This is a solid popular-level book. It’s geared more toward newish or less-advanced students of the faith, but it is devotionally edifying for anyone.

3. The Unsearchable Riches of Christ by Thomas Brooks
This is my favorite of the list. The .pdf is free online or available in a variety of print versions. Having written long ago, Brooks is not always the easiest or shortest, but he richly rewards the diligent reader.

Honorable mention: The Glory of Christ by John Owen (unabridged)
I love it. But modern readers complain he takes too long to make his points and does so with a minimum of imagination. It’s too bad because they are such excellent points! If you’ll do the work, Owen repays in spades. There are free versions online. If seeking print, I recommend an unabridged version.
