We are with you in spirit, dear parent, and we understand the concern and love you have for your son. Let's begin by praying and seeking God's will for his life. "Let us therefore come boldly to the throne of grace, that we may obtain mercy, and find grace to help in time of need" Heb 4:16 (WEB).
We need to know that Jesus is the way, the truth and the life. Without him, we have no access to the God the father. Everyone must believe on Jesus whom he has sent. Have your son believing in Jesus?
Firstly, we encourage your son to trust in the Lord and be patient. "Trust in Yahweh with all your heart, and don't lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight" Prov 3:5-6 (WEB). We need to trust that the Lord has a plan for his job situation.
Secondly, we pray that your son will be diligent in his job search. "The desire of the sluggard kills him, for his hands refuse to labor. He covets greedily all day long; but the righteous gives and doesn't withhold" Prov 21:25-26 (WEB).
We pray for open doors and divine opportunities. May the Lord direct his steps and grant him favor with potential employers.
We also pray that your son will use this time wisely, growing in his faith and relationship with the Lord. "Be still, and know that I am God" Ps 46:10 (WEB). Sometimes, periods of unemployment can be an opportunity to seek the Lord more deeply and prepare for the next season.
Finally, we encourage you both to be persistent in prayer. "Ask, and it will be given you. Seek, and you will find. Knock, and it will be opened for you" Matt 7:7 (WEB).
Lord, in the name of Jesus, we bring our petition before You. You know the situation and the needs of this family. You know your child and what employment you would have for him. Help him to trust in you. Help him to be diligent in his search. Help him to be patient. Help him to use this time wisely. Help him to seek you more deeply in the name of Jesus. Amen.
