I have always been delighted to watch birds in flight. The effortless way they spread their wings reminds me of the way God intends for us to rest in His grace. Just as birds are made for flight (Minus the Ostrich and his cousins) God intends for us to rise up by faith into the air and show off the inner beauty of Christ who lies hidden as long as we walk on the ground with our faith wings folded. And what speaks more clearly of grace than God’s Holy Sabbath? The Sabbath is a weekly reminder that on the morning when Adam and Eve rose from their first night’s sleep, God gave to them a day, and He blessed it, and called it Holy!

So God blessed the seventh day and made it holy, because on it God rested from all his work that he had done in creation. - Genesis 2:3 ESV  

And he said to them, “The Sabbath was made for man, not man for the Sabbath.
Mark 2:27 ESV

For whoever has entered God's rest has also rested from his works as God did from his.
Hebrews 4:10 ESV
