Here are two awesome messages by John Piper. The first is a teaching, based off of John 15, where Jesus calls us to abide in Him. Piper talks about the importance of memorizing scripture, and how through it, we learn how to abide in Christ.
The second is a video, where Piper talks about what it means to suffer, as a Christian, for Christ.
I highly suggest not only watching these videos entirely, but also downloading more messages from John Piper here. God has anointed this man’s mind and heart; listen to what the Lord is saying.
