Slaves to Sin or Sons to Righteousness

Sons are those who are born of the Father; a slave is one who is not born of Him, but is put to forced labor. He does not obey except by force; and they think must work for God's favor; with this mindset, there is always sin, for even the motive is wrong - how can the fruit be good? Besides we do not always do what we're supposed to. A son is one who through grace is born into the household. You are born of Him if you have believed the Gospel. Just as we have obtained our natural birth by not doing anything for it, so it is with our spiritual birth. We are made sons of God by faith in Jesus Christ.
