I came across a great article about how the Holy Spirit works in our lives...
"The Holy Spirit works through the encouragement of other believers
Nothing is more encouraging than a fellow believer who knows what it is to struggle but perseveres nonetheless. “Let us consider how we may spur one another on toward love and good deeds” (Hebrews 10:24)
The Holy Spirit works through accountability of caring, impartial friends
In nearly all cases I have known where Christians have fallen into some sort of sin, they were not accountable to anyone. We need to become vulnerable by seeking out those who are caring and impartial to whom we can be accountable. “Submit to one another” (Ephesians 5:21)
The Holy Spirit works through the church
No one that I know of is so mature and spiritual that they do not need to fellowship with the Body of Christ. Otherwise we may come to think we are above the Word, that our relationship with God bypasses the church. “Let us not give up meeting together, as some are in the habit of doing, but let us encourage one another” (Hebrews 10:25)
The Holy Spirit works through our daily, disciplined time alone with God
Whether we call it personal devotions or quiet time, we get to know God and His will largely through how much time we spend with Him. In my time alone with God, I use a Bible reading plan, one that keeps me in the Word every day. And I make it a point to spend time alone in prayer. The Bible is the Holy Spirit’s greatest product...if you want to experience the power of the Spirit to live a holy life, get to know and love the Bible more than you do anything else in the world."
