Christian calling is a high one; one that will be impossible unless we have the miracle of faith worked in our lives. This faith is the God-given, Spirit-enabled affection for Jesus Christ and trust that His promises are true to the end.
recommended memory verse: 2Cor. 4:16-18 (ESV):
So we do not lose heart. Though our outer self is wasting away, our inner self his being renewed day by day. For this light momentary affliction is preparing for us an eternal weight of glory beyond all comparison, as we look not to the things that are seen but to the things that are unseen. For the things that are seen are transient, but the things that are unseen are eternal.
