Pro 23:20 Be not among winebibbers; among riotous eaters of flesh:
Pro 23:21 For the drunkard and the glutton shall come to poverty: and drowsiness shall clothe a man with rags.
Winebibbers and riotous eaters are described as drunks and gluttons...
Php 3:19 Whose end is destruction, whose God is their belly, and whose glory is in their shame, who mind earthly things.)
Rom 16:17 Now I beseech you, brethren, mark them which cause divisions and offences contrary to the doctrine which ye have learned; and avoid them.
Rom 16:18 For they that are such serve not our Lord Jesus Christ, but their own belly; and by good words and fair speeches deceive the hearts of the simple.
Also, there are many other activities that pose risks to the human body. In fact, most forms of exercise and sports can lead to injury. Should Christians not do these things?
In moderation...
1Ti 4:8 For bodily exercise profiteth little: but godliness is profitable unto all things, having promise of the life that now is, and of that which is to come.
I'm not here to condemn since I too am guilty of some willful sins...And over eating is one of them...
The point is, God will be hard pressed to find a Christian who doesn't sin willfully at some time...And those who say they don't are lying to themselves and God...
But thank God for his Son who died that we will appear sinless before the Father...
Rom 4:6 Even as David also describeth the blessedness of the man, unto whom God imputeth righteousness without works,
Rom 4:7 Saying, Blessed are they whose iniquities are forgiven, and whose sins are covered.
Rom 4:8 Blessed is the man to whom the Lord will not impute sin.
We can be fat and still go to heaven...Our fat, smoke filled, muscle bound bodies are going to die and we will be given brand new bodies that are fit for heaven...
What’s ironic is that Catholics have told us in the past that every sin is really willful to one degree or another.
So that makes every sin mortal since there was intent behind it.
