RO 3:19 Now we know that whatever the law says, it says to those who are under the law, so that every mouth may be silenced and the whole world held accountable to God. 20 Therefore no one will be declared righteous in his sight by observing the law; rather, through the law we become conscious of sin.
Man has many true and real powers in him which some have yet to realize them. Will power is an existent power that he uses very frequently.
If one does not recognize and acknowledge that One indeed has the power of God in him, he will live as if he has no power, powerless to act against anything and everything around him.
This kind of “power” is only given by Man to another Man. The power of control is a deluded power; no Man has the power of control. He will seem to have power only when the subjects are powerless against him, when they let him have control over them.
RO 14:5 One man considers one day more sacred than another; another man considers every day alike. Each one should be fully convinced in his own mind. 6 He who regards one day as special, does so to the Lord. He who eats meat, eats to the Lord, for he gives thanks to God; and he who abstains, does so to the Lord and gives thanks to God. 7 For none of us lives to himself alone and none of us dies to himself alone. 8 If we live, we live to the Lord; and if we die, we die to the Lord. So, whether we live or die, we belong to the Lord.
RO 14:9 For this very reason, Christ died and returned to life so that he might be the Lord of both the dead and the living. 10 You, then, why do you judge your brother? Or why do you look down on your brother? For we will all stand before God's judgment seat. 11 It is written:
" `As surely as I live,' says the Lord,
`every knee will bow before me;
every tongue will confess to God.' "
RO 14:12 So then, each of us will give an account of himself to God.
RO 14:13 Therefore let us stop passing judgment on one another. Instead, make up your mind not to put any stumbling block or obstacle in your brother's way. 14 As one who is in the Lord Jesus, I am fully convinced that no food is unclean in itself. But if anyone regards something as unclean, then for him it is unclean. 15 If your brother is distressed because of what you eat, you are no longer acting in love. Do not by your eating destroy your brother for whom Christ died. 16 Do not allow what you consider good to be spoken of as evil. 17 For the kingdom of God is not a matter of eating and drinking, but of righteousness, peace and joy in the Holy Spirit, 18 because anyone who serves Christ in this way is pleasing to God and approved by men.
RO 14:19 Let us therefore make every effort to do what leads to peace and to mutual edification. 20 Do not destroy the work of God for the sake of food. All food is clean, but it is wrong for a man to eat anything that causes someone else to stumble. 21 It is better not to eat meat or drink wine or to do anything else that will cause your brother to fall.
RO 14:22 So whatever you believe about these things keep between yourself and God. Blessed is the man who does not condemn himself by what he approves. 23 But the man who has doubts is condemned if he eats, because his eating is not from faith; and everything that does not come from faith is sin.
One must recognize that the “vegetables” in the following passage does not refer to food, instead it refers to thoughts and ideas, for the wisdom of the Bible is not of the common Man’s wisdom.
RO 14:1 Accept him whose faith is weak, without passing judgment on disputable matters. 2 One man's faith allows him to eat everything, but another man, whose faith is weak, eats only vegetables. 3 The man who eats everything must not look down on him who does not, and the man who does not eat everything must not condemn the man who does, for God has accepted him. 4 Who are you to judge someone else's servant? To his own master he stands or falls. And he will stand, for the Lord is able to make him stand.
In this context, the Weak is not anyway inferior to the Strong but equal for Jesus has already stated,
MT 19:30 But many who are first will be last, and many who are last will be first.
Consider this, it takes a “weak” man more strength to stand than for a “strong” man to do the same.
Your own body and life can be taken away from you in an instant, whether it is by sickness or old age. So even if your own physical body is not for you to keep, how else would anything else be? In this physical world, only your Soul truly belongs to you.
