I think all who know that God is love, and know you, know that you are Christ's. There's no reason to doubt universal reconciliation because it is clearly stated in scripture.
"through Him to reconcile all to Him (making peace through the blood of His cross), through Him, whether those on the earth or those in the heavens" (Colossians 1:20)
"The earth" and "the heavens" means the whole universe, and it will all be reconciled to God. The only reason you doubt that is because of the strong influence of orthodox theology. Forget about that, and believe the word of God.
"For such are false apostles, fraudulent workers, being transfigured into apostles of Christ. And no marvel, for Satan himself is being transfigured into a messenger of light. It is no great thing, then, if his servants also are being transfigured as dispensers of righteousness--whose consummation shall be according to their acts." (2 Corinthians 11:13-15)
"Do not worry about anything, but in everything, by prayer and petition, with thanksgiving, let your requests be made known to God, and the peace of God, that is superior to every frame of mind, shall be garrisoning your hearts and your apprehensions in Christ Jesus." (Philippians 4:6,7)
