The 7 churches in Rev. 2 & 3 are given promises concerning those who overcome, some of which seem to be connected w/ salvation (Rev. 2:11; 3:5). Are these exhortations instructing people to overcome, or are they encouraging words reminding believers that they will overcome? Can these verses be cross referenced w/ I. Jn. 2:13; 4:4; 5:4?
