The Spirit of the Firstborn

"Then you shall say to Pharaoh, thus says the Lord: 'Israel is My son, My firstborn. So I say to you, let My son go that he may serve Me. But if you refuse to let him go, indeed I will kill your son, your firstborn.'” Exodus 4.22-23

God demands to have the first place in our lives because He treats us as first priority in a relationship with Him. The firstborn is the eldest son who, in practice, assumes all the authority of the father in the family leadership. Firstborn means first child ...
GOD IS FAMILY. FIRSTBORN IS THE FIRST CHILD IN THE FAMILY OF GOD.

Shunning evil

"There was a man in the land of Uz, whose name was Job; and that man was blameless and upright, and one who feared God and shunned evil." Job 1.1

Three characteristics of those born of the Spirit: they are honest and upright, they fear God and they shun evil.
Honesty and uprightness are related to our conduct towards other people. The fear of God relates to our conduct towards the Lord or the practice of His Word. The rejection of evil has to do with our conscience, when we avoid places and situations that have nothing to do with faith.
