Your honest cry about fear and anxiety is heard, and I am praying with you for peace and for wisdom in the days ahead.
Fear so often grows when our eyes are fixed on the threat or on the size of the decision in front of us, and when we forget who the Lord is and that He is with us. The cure for that kind of fear is to remember the Lord. David wrote that even when he walked through the valley of death he would fear no evil, because the Lord was with him. He also asked his own soul, why are you cast down and disquieted within me, and then called himself to hope in God. That is what faith does. Fear and faith cannot rule the heart at the same time. Where fear is allowed to take over, faith is pushed aside, and where there is strong confidence in God, fear loses its hold. The enemy often tries to use fear to move us to hasty or wrong actions, so it is wise not to make decisions simply because you are afraid.
You asked if you have made a mistake and if everything can happen seamlessly. God does not promise that life will always feel seamless, but He does promise to be your light, your salvation, and the strength of your life. If the Lord is your light and salvation, whom do you need to fear. He hears when His people cry to Him, He has not hidden His face from the afflicted, and His angel encamps around those who reverence Him and delivers them. Greater is He who is with you than any difficulty that is against you. You can do what is wise and prudent and commit the outcome to Him, trusting that if He intends to protect and provide, He is able to do it wherever you are.
You also mentioned financial pressure and the growth of your family. Scripture teaches that the reverent fear of the Lord is the beginning of wisdom and knowledge. It is not a cringing terror, but a holy awe that loves what God loves and hates what God calls evil, and desires to do what pleases Him. That kind of reverence brings understanding for daily decisions, including how to care for a household and how to honor God with what He has given. Those who reverence Him are told there will be no lack for what they truly need, and that He sees all we do and will provide as we walk honestly before Him. Bring your financial needs to Him plainly, ask for His provision, and also ask for wisdom to steward well what He supplies.
For your family, God gave His ways for the home because those ways build up and strengthen family relationships, while turning away from them tears families apart. Continue to seek Him together, to hate what is evil and cling to what is good, and to walk in that reverent fear of the Lord which brings health to the soul and steadiness to the home.
Above all, remember that God has made one provision for forgiveness and peace with Himself, through His Son Jesus Christ. The Spirit bears witness to our hearts that apart from Christ there is no other way to be forgiven, but through Him there is full forgiveness and a new relationship as part of God's family.
I am praying that the Lord will calm your heart as you remember Him, that He will replace fear with steady faith, that He will grant you clear wisdom for each decision, that He will provide for your daily needs and for your son as he grows, and that He will keep and guard you, your husband, your daughter and your granddaughter in His care. May He guide you step by step and let you see His faithfulness in your family in the days ahead. In Jesus name, Amen.
