Is drinking wine forbiden by God?

Ephesian 5:18 Do not get drunk on wine, which leads to debauchery. Instead, be filled with the Spirit.

I totally agree with Eph 5:18. The point here is do not get drunk, how would a person get drunk? It is when he is indulging much in wine.

1 Timothy 3:8 Deacons, likewise, are to be men worthy of respect, sincere, not indulging in much wine, and not pursuing dishonest gain.

The scripture is not contradict in itself but give us a full view of what's God's heart. Therefore it is important to be careful when drinking wine, even though I may have a knowledge that drinking wine is not forbidden by God but I'll choose not to drink wine if my action would stumble my brothers or sisters.

1 Corinthians 10:23 "Everything is permissible"—but not everything is beneficial. "Everything is permissible"—but not everything is constructive.

If God would forbade us to drink wine then he would not turn the water into wine.

John 4:46 Once more he visited Cana in Galilee, where he had turned the water into wine. And there was a certain royal official whose son lay sick at Capernaum.
John 19:29 A jar of wine vinegar was there, so they soaked a sponge in it, put the sponge on a stalk of the hyssop plant, and lifted it to Jesus' lips.

Again why Paul in his letter, asked Timothy to drink a little bit wine? Because he had a concern for his health, he knew a little bit wine was good for Timothy.

1 Timothy 5:23 Stop drinking only water, and use a little wine because of your stomach and your frequent illnesses.

How to measure how much is consider as a little bit or too much? The bottomline here is, a little bit wine is ok to drink as long as it does not affect our health or make us drunk. What God really want us to catch is the spirit rather than the form. The do's & don's are bound to failure if we do not catch the spirit/ God's heart. Can drink or can not drink is just the form, a shadow but the real spirit of it is to take good care of our health.

For God has said in 1 Cor 3:16 16 Don't you know that you yourselves are God's temple and that God's Spirit lives in you? 17If anyone destroys God's temple, God will destroy him; for God's temple is sacred, and you are that temple.
