The arm of flesh will fail you. In justification, sanctification, and regeneration. Ye dare not trust your own;
Did we in our own strength confide, our striving would be losing, Were not the right Man on our side, the man of God's own choosing. Dost ask who that may be? Christ Jesus, it is He; Lord Sabaoth, His Name, from age to age the same,
And He must win the battle.
John 6:63 (KJV)
It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life.
John 3:6 (ESV)
That which is born of the flesh is flesh, and that which is born of the Spirit is spirit.
