Christianity is the only religion where
1) what God requires OF us, he provides FOR us:
a) he requires payment for our sin, he provides payment for our sin;
b) he requires faith for salvation (Jn 3:18), he provides faith for salvation (Jn 6:65, Ac 13:48, 18:27, Php 1:29, cf Ro 12:3b, 6, 1 Co 12:3b, 2 Pe 1:1).
2) Every PRECEPT is a PROMISE (power goes along with the command):
a) "Be ye perfect (complete)" (Mt 5:48) is a promise that we shall be perfect (complete) - (Heb 10:14), sincerity being counted as gospel perfection;
b) the precept to persevere (Mt 10:22, Lk 21:19) is a promise that we shall persevere (Php 1:6, Heb 10:14, 6:17-20, Ro 8:38-39, 1 Pe 1:5, cf Lk 22:32, Ps 37:23-24, Jer 32:40) by use of the means to perseverance (2 Pe 1:5-10);
3) God crowns (rewards) his OWN grace and work in us (Php 2:12-13, Ro 1:17)), which is why we'll cast our golden crowns (rewards - 2 Tim 4:8, Jas 1:12, 1 Pe 5:4, Rev 2:10, 3:11) at the foot of his throne (Rev 4:4, 10).
Man would never have conceived of such a religion.
