Your prayer has been brought before the Lord with care and with compassion, and the burden you carry is not hidden from Him who sees all our sorrows and all our longings.
There is a weariness in your words, a sense of being pressed on every side by sensory trial, by work that is not suited to your frame, by the longing to be established as a man and to provide for yourself, and by the tension of loving parents while desiring to stand on your own feet. These things are real trials, and the Lord knows the frame of His creatures. Yet above all these needs there is one need which outweighs every other. If you have a living, loving, lasting union with the Lord Jesus Christ, you have all that you need for time and for eternity, and if you have it not, you have nothing. Take a man by himself, alone, he is lost, ruined and undone, but lay hold on Christ and you lay hold on eternal life, for He is that eternal life which was with the Father and was manifested unto us. Living contact with Him is our only hope, either for the present or for the future. Therefore I would first ask, have you been effectually called by His grace, not merely called by man but called by God, a heavenly calling that lifts up the heart to the high things of God, to eternity, heaven and holiness. This calling forbids all trust in our own doings and conducts us to Christ alone for salvation, but it afterwards purges us from dead works to serve the living and true God. If you are vitally joined to Christ, it is well with your soul, and from that union all other mercies will flow in the wisdom and timing of the Father.
Concerning your work and your desire to move toward indoor labor, voice work and other honest employment, we may pray that the Lord will open a door that is good and right for you. The Scripture teaches that we should provide for ourselves by diligent and honest labor, and that whatever our hand finds to do we should do it with all our might as unto the Lord. It is not wrong to desire work that is better suited to your constitution, where the sun and its burden and the sting of insects do not overwhelm you, and where you may labor with a quiet mind. At the same time, do not despise the present field in which God has placed you, for even there He can teach patience and humility, and He can prepare you for another field. Pray not only for a voice job or a supplementary place across the street, but pray first that you may hear the Shepherd's voice and rise up and follow Him, for the sheep hear His voice and He leads them out. When He guided you through difficult turns of the road, you will be able to bless Him and say He is truly near. Seek counsel, be diligent to improve the gifts God has given you in puppetry and voice, be faithful in small things, and trust that He who has entered into covenant for His people before they were born will also provide for your daily bread as you walk in His way.
Concerning your parents and your home, the Word of God gives two truths which must be held together. Children are to honor father and mother, and that command does not cease when we become grown, and yet a man shall leave his father and his mother and shall cleave unto his wife, and so establish his own household under God. It is right that you should desire to grow into full manhood and to bear your own responsibility, and it is right that your parents should love you and desire your good. But love must learn to release, and maturity must learn to honor. Do not strive with them as though you must wrest your freedom from their hands, but speak with them with meekness and respect, showing by steady conduct, by faithful work, by sobriety and cleanliness of life, that you are ready for greater stewardship. You mention that God knows the plans He has for you, and indeed He does, for Jeremiah declares that His thoughts toward His people are thoughts of peace and not of evil, to give you an expected end, yet that promise was given to a people called to seek the Lord with the whole heart and to walk in His ways even while in a place they did not choose. To set a date and demand that God must move you by next fall lest His plan fail is to put the servant before the Master. Rather pray, Lord, make me ready, and in Thy time lead me where I may most glorify Thee, whether that be near the place of entertainment or in a quieter place where Thou hast appointed my bounds.
Concerning your appearance and the matter of hair and the sense that others are permitted what is denied to you, remember the apostle's word, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God. If God dwells in us, let us make the house clean for so pure a God. The question is not whether others behave as they please with piercings and strange fashions, for the world will always do so, but whether you tremble at His Word and seek to be conformed to Christ. A holy trembling is a sign of life. Do not measure your walk by the hypocrisy you see in others, but by the holiness to which you are called. Whether hair be long or short, let the adornment be first a meek and quiet spirit and a life that shows you are poor in spirit and contrite, for with such the Lord says He will dwell.
We will pray for you that God would grant you salvation through Jesus Christ alone, for there is no other name under heaven given among men whereby we must be saved, that He would establish you in that living union with Christ from which all true life flows, that He would grant you a heavenly calling and make it sure to your soul, that He would give you wisdom with your parents, provision for honest work, contentment and diligence in the present, and guidance for the future, and if it be His will, that He would in His time bring to you a godly helpmeet according to His holy institution of marriage, which is the lifelong covenant of one man and one woman, and keep you pure until that day, for sex and living together belong within that covenant alone.
May the Lord who loves His people with a father's love, who guides with a father's care and bears with a father's patience, keep you and cause you to awake and still be with Him, and to talk with Him in the night watches whose eyes never slumber, until He perfects that good work which He has begun in you.
