This seems pretty unambiguous to me my brother.
Only because you're not understanding what I'm telling you... or possibly that you just refuse to. Or possibly both. God's thoughts and ways are much higher than ours (Isaiah 55:8-9), and we, like David, cannot attain to it (Psalm 139:6), so in some sense it may seem ambiguous to us, but that doesn't make it so. :)
1 Timothy 4:10 For to this end we toil and strive, because we have our hope set on the living God, who is the Savior of all people, especially of those who believe.
Well, and the "especially" can also be seen as "particularly." Yes, he's the Savior of all people, but many will never acknowledge that; they will never call upon the name of the Lord. Read Joel 2:32 and you will see the Old Testament passage that John and Paul refer to when they say, "All who call upon the name of the Lord will be saved." Here you go; the bolded part of the quote shows the limited nature of God's calling, that those who call upon the name of the Lord, will be not all, but only those whom He has called, a subset of the 'all'...
"And it shall come to pass that everyone who calls on the name of the LORD shall be saved. For in Mount Zion and in Jerusalem there shall be those who escape, as the LORD has said, and among the survivors shall be those whom the LORD calls."
There is no ambiguity.
And everybody WILL love and be with him forever.
1 Corinthians 15:28
28 When all things are subjected to him, then the Son himself will also be subjected to him who put all things in subjection under him, that God may be all in all.
That all things will be put in subjection under God is a different thing than salvation, Patrick. Closely related, but different. In eternity, Patrick, there will be those in subjection to Him with Jesus in the new heavens and new earth (with eternal life), and there will be those in subjection to Him... elsewhere, under God's final judgment, in eternal punishment. Thus, yes, all will be in subjection to Him. It is at least a bit of a frightful thought, but as John says at the end of the fifth chapter of his gospel,
"an hour is coming when all who are in the tombs will hear His voice and come out, those who have done good to the resurrection of life, and those who have done evil to the resurrection of judgment" (vv.28-29). One way or the other, yes, all will be in subjection to Him.
Grace and peace to you.
