Here is a promise.
James 2:5 Hearken, my beloved brethren, Hath not God chosen the poor of this world rich in faith, and heirs of the kingdom which he hath promised to them that love him?
If you believe this is an unconditional promise made to every Christian, then you must believe that all Christians love the Lord. Well, what does the bible say?
John 14:21-24
21 He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him.
22 Judas saith unto him, not Iscariot, Lord, how is it that thou wilt manifest thyself unto us, and not unto the world?
23 Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him.
24 He that loveth me not keepeth not my sayings: and the word which ye hear is not mine, but the Father's which sent me.
According to Jesus, if we do not keep His commandments, we do not love Him. If the kingdom is promised to them that love Him, then the kingdom is promised to them that keep His commandments. Keeping His commandments is not how we are saved, is it?
