Tell me, ye that desire to be under the law, do ye not hear the law?  For it is written, that Abraham had two sons, the one by a bondmaid, the other by a freewoman.  But he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise.  Which things are an allegory: for these are the two covenants; the one from the Mount Sinai, which gendereth to bondage, which is Agar.  For this Agar is Mount Sinai in Arabia, and answereth to Jerusalem which now is, and is in bondage with her children. But Jerusalem which is above is free, which is the mother of us all.
For it is written, “Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not: for the desolate hath many more children than she which hath an husband.”
Now we, brethren, as Isaac was, are the children of promise.  But as then he that was born after the flesh persecuted him that was born after the Spirit, even so it is now.  Nevertheless what saith the Scripture? “Cast out the bondwoman and her son: for the son of the bondwoman shall not be heir with the son of the freewoman.” So then, brethren, we are not children of the bondwoman, but of the free.  Galatians 4:21-31

O give thanks unto the LORD, for He is good: for His mercy endureth for ever.
Let the redeemed of the LORD say so, whom He hath redeemed from the hand of the enemy; and gathered them out of the lands, from the east, and from the west, from the north, and from the south.
They wandered in the wilderness in a solitary way; they found no city to dwell in.  Hungry and thirsty, their soul fainted in them.  Then they cried unto the LORD in their trouble, and He delivered them out of their distresses.  And He led them forth by the right way, that they might go to a city of habitation.
Oh that men would praise the LORD for His goodness, and for His wonderful works to the children of men!  Psalm 107:1-8

Psalms 107 and 108 along with Galatians 4 is the reading for today. Be encouraged and blessed.
