You speak of a new season, but do you know what the Lord calls seasons? At times He names the same thing both harvest and sowing, looking to one aspect then another. When He sees the ready conviction of a soul, He calls it a harvest, as if all things were already accomplished. But when He seeks the fruit of hearing and the testing of resolve, He calls it seed, and the consummation alone, harvest. Your prayer asks for the harvest before the sowing is even understood. What guilt is this you wish washed away? If it is a false guilt, born of misplaced loyalty to a love that had its own season and has now truly passed, then the truth itself gives freedom. But if the heart whispers that something is amiss, that the ground is not yet prepared, or the affections are not yet ordered according to God's design for a man and a woman in holy covenant, do not be eager to drown out that whisper with a demand for happiness.
You ask for his emotional walls to be broken down and a fresh desire for companionship to be planted. This is not a small thing. Let us consider one another to provoke unto love and good works. For as iron sharpens iron, so association of souls increases love. A stone rubbing against a stone sends forth fire; how much more soul mingled with soul? Yet this is unto the sharpening of love, not mere companionship, and of good works, that you might both acquire zeal for the Lord. If the doing has greater force for instruction than speaking, then do not simply pray for his heart to be opened to your love; pray that your life together, should it indeed be a godly path, might be a teacher of righteousness by your deeds. What is the warmth you seek? It is the loving and being loved more. But there is a commandment for this. Be kindly affectioned one to another with brotherly love. Not merely love without dissimulation, but intense and warm and glowing. Do not wait to be loved by another, but leap at it thyself. Yet that very affection grows unchangeable only by a particular path: in honor preferring one another. There is nothing which makes friends so much, as the earnest endeavor to overcome one’s neighbor in honoring him. Is this the root of your desire? To honor him in the Lord, according to His statutes, and not merely to secure his affection for a season?
Now, I hear you speak of a false sense of guilt that needs washing away, a permission to move forward. Consider, then, this solemn word. The Lord does judge the secrets of men, and those who had pleasure in unrighteousness rather than the love of the truth will be condemned at that dreadful Seat, without excuse. He calls Christ the Love of the Truth. For He came for the sake of both: as loving men, and on behalf of things that are true. If your path together is true, it will stand in the light. But if any hidden thing is not of the truth, no prayer can baptize it into righteousness. To love a benefactor and fear to trespass against him is natural. If one seeing but a man who was his benefactor an hungered, would not neglect him, how much more should we tremble at treating the commands of God lightly? The Lord will not upbraid without cause. His words on that day are in self-defense, showing He did not speak without ground. So do not think to dictate to God the removal of a guilt you have not examined. A true cleansing begins with confession and turning, not with a declaration of innocence.
Yet, I would not leave you without hope, for love has a matchless beauty that adorns the soul with every virtue. Love suffers long, and is kind; love envieth not. If a man love a wife as he ought to love, even though he be never so much inclined to wantonness, he will not endure to look upon another woman, on account of his affection for her. For love is strong as death. From no other source does wanton behavior arise than from want of love. So, if what you seek is that chaste and holy love that leads to an honorable marriage, a lifelong covenant of one man and one woman, then seek this first. Do not pray for him to have an unconditional love for you, but for both of you to have a love that is conditioned upon, and rooted in, the love and truth of God. If you have this, then any lingering sadness about the past is not a wall to be broken, but a field that has been harvested, giving thanks for what God gave in its time, while the new seed is sown.
Walk straight, then, in your hope, not doubting. If the chastisement of sorrow be of love, if it begin from loving care, it is meant to heal and not to destroy. He that runs when he is lame, galls the sore place. So do not force a forward motion that the soul is not yet healed to make. It is in our power to be thoroughly healed, but only by the right medicine. You desire him to turn the page. Let the page be turned by a clear conscience and a pure intent. To love is not enough; there must be a readiness to protect and to honor in deed. For there are many that love in mind, yet reach not forth the hand. If this relationship is to be blessed, it must be confirmative of your faith, leading you both not backward in zeal for the Lord, but forward, to build up one another in the keeping of His commandments.
Therefore, pray not for a mere feeling of permission, but for a true alignment of both your hearts to the will of the Father. Pray that if it is pleasing to Him, He will plant a love that is kind, not puffed up, not seeking its own. And in the meantime, imitate God by loving your enemy; how much more should you love with patience the one whose soul you seek to be knit to, by honoring the season of his sorrow as a work of God, not an obstacle to your own desire. In doing so, you are not just benefiting him, but obeying God who commands it. Let a deep love take root, yes, but let it be a love for God first, that out of that obedience, all other true affections might securely grow, and your journey together, if it is to be, might be a lamp unto your feet indeed.
