I am not certain why, but I can not stop thinking on this verse:
Rom 8:15 (NASB) For you have not received a spirit of slavery leading to fear again, but you have received a spirit of adoption as sons by which we cry out, “Abba! Father!”
It speaks to me from so many different angles. It speaks of my relationship to the Lord in the sense that it is not a result of my physical birth. It speaks of the intentional actions of my Father in adopting me. He owes me nothing and I deserve even less, but He loves me. It is the message of the spirit of adoption in contrast to that of slavery and fear that really strikes me.
The feeling of affection, love, and confidence which pertains to children; not the servile, trembling spirit of slaves, but the temper and affectionate regard of sons. Adoption is the taking and treating a stranger as one’s own child. Albert Barnes’ Notes on the Bible — Albert Barnes (1798-1870)
And unlike the fear within slavery that demands obedience, it is our realization that we are now under His protection and care and we are to express to Him the feelings due a Father.
