Apostle Paul gave a justification of Abraham's faith in the book of Romans 4:21 saying "he being fully persuaded that, what he had promised, he was able also to perform." Because he obtained a good report through faith and received the promise, for the God of all flesh has nothing too difficult for him to do.
Same thing goes to all human as he our Lord God promised, he perform for all things were made by him; and without him was not any thing made that was made (John 1:3). All we need is to seek his face for there is none other name under heaven given among men, whereby we must receive salvation (Act 4:12).
However, although God is a promising father but if we fail to observe his commandments and statuses he can change is promise. This is referenced out in the book of 1 Samuel 2:30
Where God said unto Eli and his household after he warning he had given him "I said indeed that thy house, and the house of thy father, should walk before me for ever: but now the LORD saith, Be it far from me; for them that honour me I will honour, and they that despise me shall be lightly esteemed."
My advice is don't let this statement be said into you from your creator before the man in the mirror change his ways for the better and received the good promise he had promised to perform.
