Rejoicing with you in God's provision through Jesus Christ and giving thanks for this open door for your studies. It is good to see your heart to serve the Lord by serving others, and to give Him glory for making a way for tuition and books. The Lord who provides is faithful, and it is right to thank Him for every part of this.
As you step into this Master's program in Human Services, remember that whatever God calls you to be and to do is the highest calling for you. There is not one calling that is higher than all others. What matters is that you are what you are by the will of God and that you are faithful in the place He has put you. If He has placed this desire and opportunity before you to grow and to help others, walk in it faithfully and humbly, and trust Him to use it for His purposes. Scripture speaks of the hope of His calling and the riches of His grace that He has prepared for those who are His, and when that hope is clear before you it gives strength and courage to keep going.
You mentioned your shoulder and the relief you have found, and that you are waiting to be connected with a physical therapist. I will pray for complete healing for you. The Bible shows that Jesus healed in many different ways, sometimes with a word, sometimes with a touch, sometimes instantly and sometimes gradually. All healing is from God, and He often works through the natural processes He built into our bodies and through the skill of doctors and therapists. That kind of care is not less spiritual. It is one of the ways God brings restoration. At the same time we know that in this fallen world there is suffering and sickness that comes indirectly because sin is in the world, not always as a direct result of something we have done. Good people still experience pain and illness, and that does not mean God has caused it. Isaiah tells us that Christ has borne our sicknesses and infirmities, and He has power over every affliction. Whether healing comes in a moment or step by step, keep bringing your body to Him in prayer and follow through with the practical help He provides.
You also shared about your travel and your desire that nothing hinder your classes. Hindrances do come, and much of the heartache we experience comes when we try to go our own way instead of listening to the Lord. There is a hymn that says what needless pain we bear when we do not carry everything to God in prayer. Bring your studies, your travel, your health, and every detail before Him, listen for His guidance, and obey what He shows you. That is how we avoid much unnecessary pain and walk in His peace.
May the Lord establish your steps in this season, give you wisdom for your studies, provide for every need, and bring healing and strength to your shoulder. May He keep you close to Jesus, make you faithful in the work He has given you, and use you to show His love to others.
