You ask for healing for your cousin, guidance in marriage, wisdom, protection, and to know the timing of when to see and speak and how all will work out. These are weighty matters, and they must be brought before the Lord with a pure heart and a right understanding of His ways.
First, concerning healing, remember that our Lord is the great physician of souls and bodies, yet He often works according to a hidden wisdom that tests and strengthens our faith. Pray without ceasing, but do not dictate the hour or the manner. Commend your cousin into His hands, and while you pray, also examine whether any waywardness has opened a door to affliction, that there might be true repentance and amendment of life. Healing of the body is good, but the healing of the soul is far greater.
As for marriage, you seek guidance and wisdom. Know this: marriage is a bond ordained by God, honorable and pure. It is not a sin, nor is it a thing to be condemned, but it is a state full of many cares. The apostle would have those who enter it do so with moderation, using it lawfully and not becoming entangled in the excesses of the world. If marriage is before you, see that your purpose is to live chastely and to raise up a godly household, not to indulge lust or to seek mere companionship apart from the fear of God. Marriage does not of itself give holiness, but it preserves the holiness that comes by faith, forbidding the defilement of fornication. So if you are already married, honor your spouse and keep the bed undefiled. If you are yet unmarried and considering it, do not act hastily, let all be done with gravity and order, not with the foolish mockeries and licentious revelries that the world introduces into wedding feasts. Let wisdom direct your steps, not passion.
You ask for wisdom and protection regarding timing: when to see, when to speak, how all will work out. Here is the wisdom that is from above: it is pure, peaceable, gentle, and full of good fruits. The wisdom of this world is foolishness with God. The world calculates, schemes, and forces doors open; but the Christian waits upon the Lord, becoming a fool to the world by refusing to trust in human cunning. Look to the Samaritan woman: she did not run ahead with brash announcements, but gently said, “Come, see,” and her timing arose from having first drunk of the living water herself. Until your own soul is quieted in God’s presence, until you have sought Him on the mountain away from the tumults of life, do not rush to speak. When the Spirit gives you a calm assurance and a fitting season, then speak with humility and love, not with anxiety or pressure. And if the result tarries, continue in prayer and patience. God foreordained a wisdom hidden before the ages for our glory. Trust His timing.
Protection will follow as you walk in peace and holiness. Flee from anything that corrupts good morals. Do not introduce the foul stench of the world’s ways into the sweet ointment of your life. Shun whatever would lead you or your cousin into sin. God will guard those who guard themselves by His commandments.
Finally, do not imagine that marriage alone, or any single event, holds the key to your happiness. Use whatever state you are in with moderation, and you may be first in the kingdom. Seek first the kingdom of God and His righteousness, and all these things will be ordered as is best for your soul. Entrust all to the grace and love of our Lord Jesus Christ, and let your constant prayer be for a will aligned with His, that whether in healing or delay, in marriage or singleness, in clear speech or silence, His name may be glorified.
