John 16:7-8: "But I tell you the truth: It is for your good that I am going away. Unless I go away, the Counselor will not come to you; but if I go, I will send him to you" (NIV).
In times of struggle, we often seek a counselor - a trusted friend or a confidant to talk with about our troubles or from whom we seek guidance and direction. The disciples saw Jesus as their counselor, and were worried when He said He was leaving them. It was then that Jesus promised the ultimate Counselor - the Holy Spirit.
Like the disciples, we are given a Counselor to teach and remind us what Jesus taught (John 14:26). The Holy Spirit is available 24/7 and is absolutely free because Jesus paid His "fee". He gives us the ability to understand our issues from Christ's perspective and He exposes the false promises of the world. He offers us "the mind of Christ" (1 Cor 2:10-16).
