"If I had cherished sin in my heart, the Lord would not have listened; but God has surely listened and heard my voice in prayer. Praise be to God, who has not rejected my prayer or withheld his love from me!" -- Psalm 66:18-20
A few years ago I installed a surround sound system in our living room. I must make it clear that I am not well experienced in wiring audio equipment and things just didn't go very well. I thought that using a staple gun would move things right along, but I failed to understand that the staples would short out the signal. After all the work was done there was the most beautiful silence you can imagine. A little staple in the wrong place can really block sweet music.
In the same way, small things can neutralize our spiritual lives in many ways. We may spend days, months and years building a great spiritual surround sound system in ministry. Everything can be well placed and look just great, but when we seek the Lord's blessing, all we find is silence. What could be the problem you might ask? Well, a little sin can really block sweet music from the Lord.
David knew that, "If I had cherished sin in my heart, the Lord would not have listened". Do we have the same conviction? May we be far more careful to maintain an unhindered communication with our Lord? David also prayed another prayer in Psalm 139:23-24 "Search me, O God, and know my heart; test me and know my anxious thoughts. See if there is any offensive way in me, and lead me in the way everlasting." Remember, a little sin can block the sweetest music of God's blessing.
