Say why is God an old man and all the other lesser gods angels I suppose look like him ?
God isn't suppose to be an old dude that is going through the aging process .
That is not a picture of Jehovah God. That is an artists rendering of Jesus. He is sporting white hair and beard to symbolize his years of life and wisdom. Those are not angels behind him, they are again an artists rendering of the 144,000 co-rulers with Jesus in heaven. Similarly they are symbolic of age and experience and faithfulness. It is a symbolic picture rendering because the 144,000 are also comprised of faithful women.
You will never see an artists rendering of Jehovah God out of respect for the Almighty. No one has ever seen God so no artists rendering of His facial features is ever made.
As far as men sporting beards now a days here is my answer: We must take into consideration that Jehovah’s people are under scrutiny by the world. The message of the Kingdom that they are taking to the people is sometimes judged by the appearance of those bringing it. There is the possibility that a Christian brother or sister dressed in a certain style might so attract the attention of the person at the door that the person does not pay attention to what the Christian is saying, or concludes that we are no different from worldlings in morals or principles. If this is the case, then the message bearer is defeating the whole purpose of his or her field service. We are called upon, at times, to sacrifice our own convenience, to a greater or lesser degree, according to the need, in order to avoid stumbling some. This was the attitude of the apostle Paul: “In no way are we giving any cause for stumbling, that our ministry might not be found fault with; but in every way we recommend ourselves as God’s ministers.”—2 Cor. 6:3, 4. A clean shaved chin has more respect as a minister of God than not. Especially now with many taking clothing and hair and even tattoos to the extreme. One could go to a door in jeans and a tank top and bare feet but one who is dressed appropriately and hair clean cut better represents our creator to take the message of the Bible to them. The Bible says we are Gods representatives and must conduct ourselves as such for the time period we live in with the highest standards possible.
