Thoughts become words. Words become actions. Actions become habits. Habits form your character. Character defines your eternities.
We need to literally picture ourselves in the arms of the Savior or coming to the judgment bar before God. If we cannot see it in our mind's eye, then we need to define what is tripping us up and focus on that first. Then go back there in the mind's eye - picture it again. Find the next thing. Keep on going until you have knocked down all obstacles. This is the definition of striving. Even if your eternal flame is dimmed to the point of near complete extinguishment, the desire alone is enough to get the journey started.
Here is the epic statement in the Book of Mormon:
14 And now behold, I ask of you, my brethren of the church, have ye spiritually been born of God? Have ye received his image in your countenances? Have ye experienced this mighty change in your hearts?
15 Do ye exercise faith in the redemption of him who created you? Do you look forward with an eye of faith, and view this mortal body raised in immortality, and this corruption raised in incorruption, to stand before God to be judged according to the deeds which have been done in the mortal body?16 I say unto you, can you imagine to yourselves that ye hear the voice of the Lord, saying unto you, in that day: Come unto me ye blessed, for behold, your works have been the works of righteousness upon the face of the earth?17 Or do ye imagine to yourselves that ye can lie unto the Lord in that day, and say—Lord, our works have been righteous works upon the face of the earth—and that he will save you?18 Or otherwise, can ye imagine yourselves brought before the tribunal of God with your souls filled with guilt and remorse, having a remembrance of all your guilt, yea, a perfect remembrance of all your wickedness, yea, a remembrance that ye have set at defiance the commandments of God?19 I say unto you, can ye look up to God at that day with a pure heart and clean hands? I say unto you, can you look up, having the image of God engraven upon your countenances?20 I say unto you, can ye think of being saved when you have yielded yourselves to become subjects to the devil?21 I say unto you, ye will know at that day that ye cannot be saved; for there can no man be saved except his garments are washed white; yea, his garments must be purified until they are cleansed from all stain, through the blood of him of whom it has been spoken by our fathers, who should come to redeem his people from their sins.22 And now I ask of you, my brethren, how will any of you feel, if ye shall stand before the bar of God, having your garments stained with blood and all manner of filthiness? Behold, what will these things testify against you?23 Behold will they not testify that ye are murderers, yea, and also that ye are guilty of all manner of wickedness?24 Behold, my brethren, do ye suppose that such an one can have a place to sit down in the kingdom of God, with Abraham, with Isaac, and with Jacob, and also all the holy prophets, whose garments are cleansed and are spotless, pure and white?25 I say unto you, Nay; except ye make our Creator a liar from the beginning, or suppose that he is a liar from the beginning, ye cannot suppose that such can have place in the kingdom of heaven; but they shall be cast out for they are the children of the kingdom of the devil.26 And now behold, I say unto you, my brethren, if ye have experienced a change of heart, and if ye have felt to sing the song of redeeming love, I would ask, can ye feel so now?27 Have ye walked, keeping yourselves blameless before God? Could ye say, if ye were called to die at this time, within yourselves, that ye have been sufficiently humble? That your garments have been cleansed and made white through the blood of Christ, who will come to redeem his people from their sins?28 Behold, are ye stripped of pride? I say unto you, if ye are not ye are not prepared to meet God. Behold ye must prepare quickly; for the kingdom of heaven is soon at hand, and such an one hath not eternal life.29 Behold, I say, is there one among you who is not stripped of envy? I say unto you that such an one is not prepared; and I would that he should prepare quickly, for the hour is close at hand, and he knoweth not when the time shall come; for such an one is not found guiltless.30 And again I say unto you, is there one among you that doth make a mock of his brother, or that heapeth upon him persecutions?31 Wo unto such an one, for he is not prepared, and the time is at hand that he must repent or he cannot be saved!33 Behold, he sendeth an invitation unto all men, for the arms of mercy are extended towards them, and he saith: Repent, and I will receive you.34 Yea, he saith: Come unto me and ye shall partake of the fruit of the tree of life; yea, ye shall eat and drink of the bread and the waters of life freely;35 Yea, come unto me and bring forth works of righteousness, and ye shall not be hewn down and cast into the fire—36 For behold, the time is at hand that whosoever bringeth forth not good fruit, or whosoever doeth not the works of righteousness, the same have cause to wail and mourn.37 O ye workers of iniquity; ye that are puffed up in the vain things of the world, ye that have professed to have known the ways of righteousness nevertheless have gone astray, as sheep having no shepherd, notwithstanding a shepherd hath called after you and is still calling after you, but ye will not hearken unto his voice!38 Behold, I say unto you, that the good shepherd doth call you; yea, and in his own name he doth call you, which is the name of Christ; and if ye will not hearken unto the voice of the good shepherd, to the name by which ye are called, behold, ye are not the sheep of the good shepherd.39 And now if ye are not the sheep of the good shepherd, of what fold are ye? Behold, I say unto you, that the devil is your shepherd, and ye are of his fold; and now, who can deny this? Behold, I say unto you, whosoever denieth this is a liar and a child of the devil.40 For I say unto you that whatsoever is good cometh from God, and whatsoever is evil cometh from the devil.41 Therefore, if a man bringeth forth good works he hearkeneth unto the voice of the good shepherd, and he doth follow him; but whosoever bringeth forth evil works, the same becometh a child of the devil, for he hearkeneth unto his voice, and doth follow him.42 And whosoever doeth this must receive his wages of him; therefore, for his wages he receiveth death, as to things pertaining unto righteousness, being dead unto all good works.
