You might have noticed I have just added a list on the right panel - Theological Candyland - a term I borrowed from Faith by Hearing, where I have been updating my collection of audio mp3s. I am currently listening to Gordon D. Fee's Reading and Studying the Bible for Life.
There are just so much resources out there - we just need to know where to find the good ones. I have listed several sites that provide excellent resources in expository preaching, sermons and theology & biblical studies.
Hope you will find gems as well and make full use of them to strengthen your foundation and relationship with the LORD.
