Jesus is a god but is not the Almighty God. Only the Father ("whose name alone is Jehovah" Ps. 83:18; - KJV) is Almighty God..."the only true God". (John 17:3)
The inspired scriptures when speaking of faithful angels, prophets, God-appointed judges, kings, and magistrates clearly call them "gods" on occasion. These are called "gods" in the sense of faithful servants of God, representing the true God. (Ps. 8:5; 97:7; 138:1); Ps. 82:1, 6... and also John 10:34-36)
Young's Analytical Concordance of the Bible, Eerdmans, 1978 Reprint, "Hints and Helps to Bible Interpretation":
"65. GOD - is used of any one (professedly) MIGHTY, whether truly so or not, and is applied not only to the true God, but to false gods, magistrates, judges, angels, prophets, etc., e.g. - Exod. 7:1; 15:11; 21:6; 22:8, 9;...Ps. 8:5; 45:6; 82:1, 6; 97:7, 9...John 1:1; 10:33, 34, 35; 20:28...."
Strong's Exhaustive Concordance of the Bible, Abingdon, 1974 printing:
"430. [elohim]. el-o-heem'; plural of 433; gods in the ordinary sense; but spec. used (in the plur. thus, esp. with the art.) of the supreme God; occasionally applied by way of deference to magistrates; and sometimes as a superlative: - angels, ... x (very) great, judges, x mighty." - p. 12, "Hebrew and Chaldee Dictionary."
