food

Kingdom of God is not eating and drinking

For if because of food your brother is hurt, you are no longer walking according to love. Do not destroy with your food him for whom Christ died.

Therefore do not let what is for you a good thing be spoken of as evil;

for the kingdom of God is not eating and drinking, but righteousness and peace and joy in the Holy Spirit.

Romans 14:15-17 (NASB)

Milk or solid food?

For everyone who partakes only of milk is not accustomed to the word of righteousness, for he is an infant.

But solid food is for the mature, who because of practice have their senses trained to discern good and evil.

Hebrews 5:13-14 (NASB)
