I do not believe we have yet seen the glory and fullness of the outpouring of the Holy Spirit as prophesied by Joel. What we have seen are just a few sprinkles! The power and love of the Holy Spirit have brought many together throughout the world, yet it is just a foretaste. God has much more in store for us.
The outpouring of the Holy Spirit will not be just a renewal of love and praise; it will be a restoration of holiness unto the Lord. God will permit nothing to hinder what he plans to do, and his intent is to raise up a standard against the enemy when he comes in “like a flood” (see Isaiah 59:19). What is that standard? It is a holy people who are pure, undefiled and delivered from the corruption of the world. We will not have the fullness of the Spirit's outpouring, and we will not be able to stand against the enemy, until God’s people separate themselves completely from the world.
Tragically, too many people have an initial encounter with God but do not try to live a holy life afterward. They may speak with tongues, but then they live like the devil. Sin is not uprooted from their hearts, and all they receive is an experience of ecstasy. You are not truly baptized with the Holy Spirit until every hidden part of your soul has been exposed, and every sin confessed and forsaken.
We must emphasize separation and purity of heart. The purpose of the Spirit's coming is to sanctify and prepare a people for the Lord's return, a people without spot or wrinkle. He will “convict the world of sin, and of righteousness, and of judgment” (John 16:8, NKJV). This is the fullness of the Holy Spirit’s work: renewal and sanctification!
God wants us to be led by the Spirit into a deeper, more mature life that is consecrated to him. When we seek this sanctified life, we will be mightily used by God to shine forth as lights to this wicked and perverse generation.
