"Thy faithfulness reacheth unto the clouds" (Psalm 36:5).
One might think that the more accurate imagery would be that God's faithfulness reacheth from the clouds, or from beyond the clouds. David nevertheless speaks of our Heavenly Father's devotion to us as ascending upward, as from the earth rather than descending downward to us from Heaven.
Certainly God is in His Heaven, but He is also in and upon His earth.
"Whither shall I go from Thy Spirit? Or whither shall I flee from Thy presence? If I ascend up into heaven, Thou art there: if I make my bed in hell, behold, Thou art there. If I take the wings of the morning, and dwell in the uttermost parts of the sea; even there shall Thy hand lead me, and Thy right hand shall hold me" (Psalm 139:7-10).
The first expression of faithfulness is simply showing up. God always shows up. He is always there, awaiting our arrival at scenes He anticipated from eternity past. Indeed, born again believers in the Lord Jesus Christ will never experience a moment wherein God will be absent, or need to be summoned to our side. Our lives are rather saturated with His loving involvement, to the degree that "in Him we live and move and have our being" (Acts 17:28). His faithfulness reaches unto the clouds because it is here with us in measureless devotion to our benefit and well being.
We will know and experience this gift of grace to the degree we believe and expect it to be the great fact of our existence. Faith opens the eyes of the heart to see the invisible, and to know a spiritual substance far more genuinely tangible than any outward, visible thing. We live our lives in the environment of God's perfect faithfulness and an involvement so devoted that we look upward and cannot see its apex. Because it "reacheth unto the clouds..."
"God is faithful."
(I Corinthians 13:10)
