7 Nevertheless I tell you the truth. It is to your advantage that I go away; for if I do not go away, the Helper will not come to you; but if I depart, I will send Him to you. 8 And when He has come, He will convict the world of sin, and of righteousness, and of judgment: 9 of sin, because they do not believe in Me; 10 of righteousness, because I go to My Father and you see Me no more; 11 of judgment, because the ruler of this world is judged.
Holy Spirit is our lifeline in our spiritual growth. If this lifeline is not flowing well, then we will be either lame or dead. How the Helper does help us to know Christ? Through conviction and guidance. He will convict us about the sin and lead us in the path of holiness; He will convict us about the righteousness and lead us into His righteousness. He will convict us about the judgment and lead us in all truth.
When we are baptized in the Holy Spirit, the knowledge of Christ in us grows exponentially and quickly. It will quicken the process to achieve the fullness in Christ. Whatever we saw past few days about knowing Christ will become clearer and uplifting.
