Freedom and responsibility

Romans 14:1-23
Do not judge someone else's servant. To his own master he stands or falls.
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. We are the servant of the Lord.
Every knee will bow before me; every tongue will confess to God. (Isaiah 45:23)
For the kingdom of god is not a matter of eating and drinking, but of righteousness, peace and joy in the Holy Spirit.
Blessed is the man who does not condemn himself by what he approves. Everything that does not come from faith is sin.
There are some matters of conscience over which Christians disagree. It is not helpful to argue over 'doubtful points'.
Those who are strong in the faith may feel free to do things that would give others a bad conscience. This is not reason to despise them. Neither side should pass judgment on the other.
All of us, Paul says, are answerable, not to one another, but to Christ. It is better to limit our own freedom than exercise it at a fellow Christian's expense.
Why?
We are servant of God so we have not right to judge other servant of the Lord.
Eating and drinking is not a matter in the kingdom of God, but the righteousness, peace and joy in the Holy Spirit.
Our freedom in faith should not be stumbling to others in weak faith.
Do the things that are right between me and the Lord.
How?
Talk to others with peace and joy, do not judge others. pursue the righteousess and pease and joy in Holy Spirit.
