Romans 14:5-12 (NKJV)
5 One person esteems one day above another; another esteems every day alike. Let each be fully convinced in his own mind. 6 He who observes the day, observes it to the Lord; [a]and he who does not observe the day, to the Lord he does not observe it. He who eats, eats to the Lord, for he gives God thanks; and he who does not eat, to the Lord he does not eat, and gives God thanks. 7 For none of us lives to himself, and no one dies to himself. 8 For if we live, we live to the Lord; and if we die, we die to the Lord. Therefore, whether we live or die, we are the Lord’s. 9 For to this end Christ died [b]and rose and lived again, that He might be Lord of both the dead and the living. 10 But why do you judge your brother? Or why do you show contempt for your brother? For we shall all stand before the judgment seat of [c]Christ. 11 For it is written:
“As I live, says the Lord,
Every knee shall bow to Me,
And every tongue shall confess to God.”
12 So then each of us shall give account of himself to God.
James 4:13-17 (NKJV)
Do Not Boast About Tomorrow
13 Come now, you who say, “Today or tomorrow [a]we will go to such and such a city, spend a year there, buy and sell, and make a profit”; 14 whereas you do not know what will happen tomorrow. For what is your life? It is even a vapor that appears for a little time and then vanishes away. 15 Instead you ought to say, “If the Lord wills, we shall live and do this or that.” 16 But now you boast in your arrogance. All such boasting is evil.
17 Therefore, to him who knows to do good and does not do it, to him it is sin.
