"What can we assume will happen if we grieve or quench the Spirit's power in our lives?"
Here are Paul's thoughts on this, found in Ephesians 3:14-19:
what is the breadth and length and height and depth, and to know the love of Christ that surpasses knowledge,
B. so that you may be filled with all the fullness of God.
Conversely, if we quench the Spirit:
1. We will not be strengthened with the power to love, leading to selfishness.
2. We will not be strengthened to comprehend his love, leading to insecurity, which leads to control, which leads to narcissism (self-preservation only). And if everyone does this, then there is no charity, except to promote oneself.
3. We will not be filled with the fulness of God, leading to you missing all that God wants you to be. Some characteristics that the fulness of God brings is: love, joy, peace, patience, kindness, goodness, gentleness, faithfulness, and self-control.
So how do we hamstring the Spirit's power in our lives?
1. By disbelief and rejecting God's means of salvation. Dependance in Jesus the Savior (Messiah) to save you too.
2. By building your life on something other than the teachings of Jesus.
3. By following base passions without yielding to the Spirit (see Galatians 5). Also known as "animal instincts".
4. By not seeking God, or extreme introversion (thus ignoring loving people and entering into their lives).
5. By allowing your mind to dwell on things that oppose Scripture (i.e. books that teach twisted theology like The Shack, The Art of Happiness, 50 Shades, lop-sided political books or activist books, etc..).
My dear friends, let us not lose focus, thus hurting ourselves and others. Instead, let's get refocused on what is good, healthy, and life-giving.
