Hebrews 12:9 Furthermore we have had fathers of our flesh which corrected us, and we gave them reverence: shall we not much rather be in subjection unto the Father of spirits, and live? 

‘Shall we not much rather be in subjection unto the Father of spirits, and live?’ True chastening or correction is by learning the will of God through the Word and by the Holy Spirit. As we live in the Spirit we are led, taught, and shown the will of God daily (John 14:16-17, 26; 15:26; 16:7-15; Rom. 6:16-23; 8:1-26; 1Jn. 1:7). This is proper and true child training, and if one rebels he has to be dealt with according to his sowing (Gal. 6:7-8).

‘The Father of spirits.’ Sets forth the biblical doctrine of the immortality of the souls and spirits of all men, and the distinct difference between the material and spiritual natures of man (Num. 16:22; Isa. 42:5; Zech. 12:1; Heb. 12:23). All souls and spirits are in the keeping of God (Eccl. 12:7). Those who have already left their bodies (Jas. 2:26) are either in hell awaiting their resurrection (Isa. 14:9; Luke 16:19-31), or in paradise awaiting the resurrection (2Cor. 5:8; Php. 1:21-24). God will have the final say as to their destiny (2Cor. 5:9-10; Rev. 20:11-15).
