The word for God/god in Genesis 1:26 is elohiym which is used all though out the Bible.
OT:430
'elohiym (el-o-heem'); plural of OT:433; gods in the ordinary sense; but specifically used (in the plural thus, especially with the article) of the supreme God; occasionally applied by way of deference to magistrates; and sometimes as a superlative:
Notice the word “pluralâ€Â, that is where they get the us. This is quite a debate what men perceive as Elohim… Sometimes this word has a capital “G†other times a lower caseâ€Âgâ€Â. In Ps. 82 it is used with a lower case’s’.
Let us make us is the Hebrew word “asah†OT:6213
`asah (aw-saw'); a primitive root; to do or make, in the broadest sense and widest application (as follows):
KJV - accomplish, advance, appoint, apt, be at, become, bear, bestow, bring forth, bruise, be busy, X certainly, have the charge of, commit, deal (with), deck, + displease, do, (ready) dress (-ed), (put in) execute (-ion), exercise, fashion, + feast, [fighting-] man, + finish, fit, fly, follow, fulfill, furnish, gather, get, go about, govern, grant, great, + hinder, hold ([a feast]), X indeed, + be industrious, + journey, keep, labour, maintain, make, be meet, observe, be occupied, offer, + officer, pare, bring (come) to pass, perform, pracise, prepare, procure, provide, put, requite, X sacrifice, serve, set, shew, X sin, spend, X surely, take, X thoroughly, trim, X very, + vex, be [warr-] ior, work (-man), yield, use.
There are many names and descriptive titles of God in the scriptures. He is called Counselor, King, Shepherd, Rock, Shield, High Tower, Strong Arm, Saviour, Redeemer, Father, Yahweh, Elohim, El Shaddai, El Elyon, Jesus (Yahshua), and many, many others. Someone has said that there are about two hundred names for God in the Bible! The moment one begins to splinter the absolute wholeness that God is, to examine all His multi-faceted aspects and attributes, the number of splinters are as infinite as God is infinite. Each name of God, as He progressively revealed Himself, was a fresh and fuller revelation of the nature of God. One was a revelation of His Self-existence, another of His might, another was the unveiling of His grace. One revealed something more of His wisdom, another of His holiness, another of His tenderness, another of His exaltation and honor, another of His judgment, and so on.
Psalm 82
1 God standeth in the congregation of the mighty; he judgeth among the gods. (notice little “g†or Elohim)
2 How long will ye judge unjustly, and accept the persons of the wicked? Selah.
3 Defend the poor and fatherless: do justice to the afflicted and needy.
4 Deliver the poor and needy: rid them out of the hand of the wicked.
5 They know not, neither will they understand; they walk on in darkness: all the foundations of the earth are out of course.
6 I have said, Ye are gods (Elohim); and all of you are children of the most High.
7 But ye shall die like men, and fall like one of the princes.
8 Arise, O God, judge the earth: for thou shalt inherit all nations.
Ed the Ned said:
Genesis 1 vs 26 "Then God said 'Let us make man in our image, after our likeness'"
Does that not prove that God is more than one? That he consists of the father, the son and the Holy Spirit.
