“For as high as the heavens are above the earth, so great is His lovingkindness toward those who fear Him” (Psalm 103:11).
In 2009 astronomers detected the most distant object yet seen from Earth. It was a gamma ray burst. The rays from that explosion took 13 billion years to reach the earth. When David wrote this Psalm, he had no idea how high the heavens were above the earth. But he knew the grace of God and that the heavens were unable to contain its vastness.
