It is very positive act to build up. Wherefore, accept one another, just as Christ also accepted us to the glory of God. Christ died for them as well. They are precious in the sight of God. Our acceptance and care for one another brings glory to God, by serving others rather than selfishly satisfying only ourselves.
Love is about giving good things, and helping one another to discard bad things.
Christ has helped taking our sins and guilt away. You also should help our brethren to become pure and holy to the Glory of God. One may even journey to another congregation, by the calling, vision, prophesy of God, to serve the brethren who are far off. Do not just occupy yourselves with things nearby. Develop long vision, and be attentive to need arise around you.
