First Revealing
And they (Adam and Eve) heard the sound of the LORD God walking in the garden in the cool of the day . . .
And he (Adam) said, "I heard You (God) walking in the garden, and I was afraid because I am naked . . ." (Genesis 3:8, 10, HBFV throughout).
The above verses reveal that God not only had legs, but also that his feet made a sound when it hit the ground that alerted the first humans he was approaching.
An Unusual Request
Moses, after he successfully pleaded with God to continue personally leading the Israelites to the Promised Land, made a unusual request.
And he (Moses) said, "I beseech You, show me Your glory." (Exodus 33:18).
Moses had seen the glory of God on several occasions preceeding his request (Exodus 24:9, 11, 15 - 18, etc.). What Moses wanted was to experience more of his actual form, to see what he looked like in spirit. The response he received was amazing!
"I will make all My goodness pass before you, and I will proclaim the name of the LORD before you . . . You cannot see My face, for no man can see Me and live . . ."
"And it will be, while My glory passes by, I will put you in a cleft of the rock, and will cover you with My hand while I pass by. And I will take away My hand, and you shall see My back parts. But My face shall not be seen." (Exodus 33:19 - 20, 22 - 23).
The above tells us that God, in his spiritual form, has a head, face, hands, back, legs and back parts just like a human!
The Transfiguration
The transfiguration is the miraculous manifestation of Jesus' glory as a member of the Godhead along with the glorified forms of Moses and Elijah. This manifestation was witnessed by Peter, James and John who were on a high mountain when the event took place.
And He was transfigured before them; and His face shined as the sun, and His garments became white as the light (Matthew 17:2, see also Mark 9:1 - 10, Luke 9:27 - 36).
Note that Jesus, when he showed his glorified form, did not become a blob or take on some shape that was unrecognizable to the apostles. He had the same head, arms, eyes, nose, mouth, torso, legs and overall look he had as a human except in their glorified spiritual composition.
Other References
There are plenty of other places in the Bible that reveal the various parts of what God (the Father and Jesus Christ) looks like as a spirit being.
God is recorded as possessing a head (Revelation 19:12, 1:14, Jeremiah 19:5, 32:35) which has a face (Deuteronomy 34:10, Genesis 33:10) and hair (Daniel 7:9, Revelation 1:14). He also has eyes (Revelation 1:14, Psalm 11:4, 18:24), ears (Psalm 18:6, 34:15), a mouth (Numbers 12:8, Isaiah 1:20), lips (Isaiah 11:4, 30:27) and a tongue (Isaiah 30:27).
God also possesses arms (Psalm 44:3, John 12:38) which have hands (Psalm 102:25 - 26, Hebrews 1:10) and fingers (Exodus 31:18, Psalm 8:3 - 6). The Godhead additionally has loins (Ezekiel 1:26 - 28, 8:1 - 4) as well as feet (Psalm 18:9, Ezekiel 1:26, 1Corinthians 15:27).
Conclusion
God created mankind in his image and after his own likeness (Genesis 1:26). This means that it is not that we look like God, but rather that the Godhead chose to pattern humans after themselves.
