Just days ago we had read kjv@1Corinthians:15 that the righteousness of God in putting us through this corruption was to break us down, have us die to ourselves that we might germinate to a spiritual plant/being (be born again). Here it says similarly the travail God has given the sons of men to be exercised with. From the observation from heaven it is a unnecessary and righteous thing and from our sense it is a grievous and sorrowful thing. This is because of the weight with which we invest ourselves into making something carnal out of this present corruption. We do not see the things under heaven as they were before nor the things as they will be. All is vanity, but, God submitted us to this vanity because of a much greater righteous hope kjv@Romans:8:20-23.
Peter kjv@2Peter:1:4 described this world as a corruption that is in this world because of lust. Corruption can mean death and decay as it does for the sons of the lusting to be wise Adam/Eve. The thought of this death makes us to lust for all that we might have and make out of this short time which brings us to a corruption of all that is good and intended; lust upon lust and it's many other corruptions. What God has done by putting us through this is to be looked at in terms of forever that men should fear Him; a tremendously good and righteous work of making us righteous within the righteousness of His Son; raising us up from this corruption much as His Son a new spiritual creature. From this nothing can be put to nor taken away.
There are concerns that the sons of God mentioned here may have been fallen angels; an intra species race. It would lend a different understanding to why the flood would be immediately necessary if true. Others see these giants to be plain men of unusual stature and influence.
