Thank God that He freely gives us the Spirit when we ask. Not that anyone who is a Chritian doesn't have the Spirit dwelling in them once they choose to follow the path of Christ. That's mysterious, but theologically true.
But there is something cool about awakening our awareness of the work of the Spirit to counsel, comfort, strenghthen, and guide, and to call on His power to help us in every circumstance. That is where deep joy and peace come from, as well as the ability to respond with grace and let mercy lead.
Which reminds me of a Rich Mullins tune off of his Brother's Keeper album.
Let mercy lead, let love be the strength in your legs,
And in every footprint that you leave
There'll be a drop of grace;
If we can reach
Beyond the wisdom of this age
Into the foolishness of God
That foolishness will save those who believe,
In that foolish grace of God they will find peace
And He'll meet them
In that place where mercy leads.
I always loved that tune - particularly the idea of leaving footprints filled with drops of grace.
May it be so, not by might, not by strength, but by the power of the Spirit of God.
