The truth is no one has an excuse because everyone is given their fair chances to find the truth and everyone who seeks the truth can find it I don’t know if anyone would not have been given enough knowledge of ones duty throughout one life to have an excuse but if that is the case I believe if one genuinely wanted the truth God would reveal it to one who is seeking later before they die or even if that is in one last breath when they are unconscious but still alive still having breath
Jesus said narrow is the gate and difficult is the way that leads to life and there are few who find it.
People have to seek the truth to find it some will be shown the truth and should respond if not they may find it harder to find truth before they die if they did not seek while they can if they had all their chances God may give more chances to some if he thinks they deserve it to find it more easily later if he wants to give it to them then but one can not presume he will for he may have given chances to one before to seek and to know and one has to therefore seek to believe because one may not deserve further chances to believe if God thinks one has got all one chances which we are to assume all our chances are fair for those who have been counseled to seek may not get further opportunity for one has to actually seek but God can give opportunity to whoever deserves it. It is difficult because you are required to follow Christ once you know the truth it is your choice if you do not you may die earlier while not making decision because not everyone will deserve chance to find it later. Everyone is responsible to seek the truth and is in danger because he does not know if he is given his chances and so does not know if he will be given his chances later
Some may not worship actual physical idols but they do not worship the true God who can be known Jesus said you have to worship in spirit and truth. God requires people to know true God as Jesus says that they may know you know you the only true God and Jesus Christ whom you sent for Jesus is the way the truth and the life without believing in His redemption for forgiveness of sins and being made new people people can not enter kingdom of God if other religions are not ways to God a religion which says all ways lead to God is not true either
Acts 17:23-31
23 Therefore, the One whom you worship without knowing, Him I proclaim to you: 24 God, who made the world and everything in it, since He is Lord of heaven and earth, does not dwell in temples made with hands. 25 Nor is He worshiped with men’s hands, as though He needed anything, since He gives to all life, breath, and all things. 26 And He has made from one blood every nation of men to dwell on all the face of the earth, and has determined their preappointed times and the boundaries of their dwellings, 27 so that they should seek the Lord, in the hope that they might grope for Him and find Him, though He is not far from each one of us; 28 for in Him we live and move and have our being, as also some of your own poets have said, ‘For we are also His offspring.’ 29 Therefore, since we are the offspring of God, we ought not to think that the Divine Nature is like gold or silver or stone, something shaped by art and man’s devising. 30 Truly, these times of ignorance God overlooked, but now commands all men everywhere to repent, 31 because He has appointed a day on which He will judge the world in righteousness by the Man whom He has ordained. He has given assurance of this to all by raising Him from the dead
I said before
It is difficult because you are required to follow Christ once you know the truth it is your choice if you do not you may die earlier while not making decision because not everyone will deserve chance to find it later.
I suppose it is still always available to accept to believe in but devil can seek to deceive people to not make people accept it or willing to accept it and it is still necessary to do will of God which one does not know if one keeps delaying whether one will have done it before one dies and one can die at a time he does not expect whether soon or not and if one never strived while he had opportunity because one never knows when that opportunity remains he can have died when he is not living in Christ and did not do the will of God
