Romans 14:1

1Accept him whose faith is weak, without passing judgment on disputable matters. 2One man's faith allows him to eat everything, but another man, whose faith is weak, eats only vegetables. 3The man who eats everything must not look down on him who does not, and the man who does not eat everything must not condemn the man who does, for God has accepted him. 4Who are you to judge someone else's servant? To his own master he stands or falls. And he will stand, for the Lord is able to make him stand.

5One man considers one day more sacred than another; another man considers every day alike. Each one should be fully convinced in his own mind. 6He who regards one day as special, does so to the Lord. He who eats meat, eats to the Lord, for he gives thanks to God; and he who abstains, does so to the Lord and gives thanks to God. 7For none of us lives to himself alone and none of us dies to himself alone. 8 If we live, we live to the Lord; and if we die, we die to the Lord. So, whether we live or die, we belong to the Lord.

9For this very reason, Christ died and returned to life so that he might be the Lord of both the dead and the living. 10You, then, why do you judge your brother? Or why do you look down on your brother? For we will all stand before God's judgment seat. 11It is written:
" 'As surely as I live,' says the Lord,
'every knee will bow before me;
every tongue will confess to God.' "[a] 12So then, each of us will give an account of himself to God.

..One of my favorite chapters, I only post it here because it's folly to argue about non-essential doctrine. Believing pre-trib, or post-trib does not make one an evil doer. And it's pointless to argue the matter if it makes others weak in their faith.

Regardless we are told to watch for Him always and treat it as imminent.
