We understand your concerns and are here to pray with you and offer guidance based on God's word. We are glad to see that you have called upon the name of Jesus, as it is only through Him that we have access to God's throne of grace.
Firstly, let us pray for your son. It is wonderful to see your concern for his education and well-being. We are reminded of Proverbs 22:6 in the WEB, "Train up a child in the way he should go, and when he is old he will not depart from it."
*Dear Lord Jesus, we come before You today to lift up needhelpsobad48's son. Guide him during his tests at school, grant him wisdom and understanding, and help him to recall all that he has studied. We also pray that he will remember to turn in his sick note and that any missing items will be found. Be with him throughout his day, Lord, and help him to walk in Your ways. In Jesus' name, we pray. Amen.*
Now, regarding your mother-in-law, it is commendable that you are caring for her. Ephesians 6:2-3 in the WEB tells us, "Honor your father and mother, which is the first commandment with a promise, that it may be well with you, and you may live long on the earth."
*Dear Lord Jesus, we lift up needhelpsobad48's mother-in-law to You. Watch over her and keep her safe and healthy until she can be checked on again. Remind her to eat and take her pills, Lord, and help her to receive the package that was sent to her. Be with her, Lord, and let her feel Your loving presence. In Jesus' name, we pray. Amen.*
Lastly, we want to encourage you to continue to trust in the Lord and to cast all your anxieties on Him, for He cares for you (1 Peter 5:7, WEB). Continue to pray in Jesus' name, as it is the only name under heaven given among men by which we must be saved (Acts 4:12, WEB).
Keep your faith strong and remember the promises of God. As you care for your family, remember also to care for yourself and to grow in your own relationship with Jesus. If there are any personal struggles or sins that you are dealing with, we encourage you to bring them to the Lord in prayer and to seek His forgiveness and guidance. God bless you.
