Everlasting Father is a good one for Jesus only cult yes.But I am not.I actually came across one of those who used that verse,but there are two ways of looking at it from a Trinatarian point of view:1.Jesus is the Father of everlasting life i.e. it is by him we achieve everlasting life.And 2nd,the childs source is from the Everlasting Father.
Now friend,Abraham was,I AM.This isn't saying Jesus-Only.But they are one.I know it sounds illogical to you but its very simple.Like a triangle has 3 corners it is still one.Why did many people worship him and he permitted them?If he were not God,that would contradict Revelation when John worships the angel,and the angel says don't do it!Worship God!Now you ll probably say why did they worship Peter?The Holy Ghost was being worshipped my friend.If you go throughout the whole Bible you'll find patterns of three.That very scripture you gave me:Hear O Israel the Lord our God,the Lord is One.
Lord,God,Lord is One.We could go through Genesis to Revelation and find the Trinity in there.
Now since you think Jesus Only is a cult,what about yours?Its the same thing a weird and offshoot version of Christianity.
And I say this with grace,if I ever come off a bit hawckish forgive me,I don't hate anybody,just the beliefs.
