So then who according to Paul should be the ones complaining that they 'cannot submit to the Law of God"??
Rom 8
6 For the mind set on the flesh is death, but the mind set on the Spirit is life and peace, 7 because the mind set on the flesh is hostile toward God; for it does not subject itself to the law of God, for it is not even able to do so, 8 and those who are in the flesh cannot please God.
So then - why don't these sources whine and complain that God's Commandments "cannot be kept"??
I Thomas Watson, the Seventh-day Baptists, the Baptist Confession of Faith, C.H. Spurgeon, Andy Stanley, the Westminster Confession of Faith  , D.L. Moody, R. C Sproul etc.
Possibly they read Rom 8:6-8 without choosing to be at war with it.
in Christ,
Bob
