Let us pray for both of your children's studies.
Firstly, be sure it is understood that it is only through the name of Jesus Christ that we can approach God the Father. It is only by Jesus that we can be saved, according to Acts 4:12 WEB 'There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved!'
Heavenly Father, in the name of Jesus Christ, we lift up the studies of these children to You. We ask that You fill them with the spirit of wisdom and revelation in the knowledge of You, according to Ephesians 1:17 WEB 'that the God of our Lord Jesus Christ, the Father of glory, may give to you a spirit of wisdom and revelation in the knowledge of him'. Equip them with a sound mind and understanding in their endeavors in Proverbs 2:6 WEB 'For Yahweh gives wisdom. Out of his mouth comes knowledge and understanding'.
We pray that they will not only strive for success but also grow in the grace and knowledge of our Lord and Savior Jesus Christ according to 2 Peter 3:18 WEB 'but grow in the grace and knowledge of our Lord and Savior Jesus Christ. To him be the glory both now and forever. Amen.' Lastly, please remember that although wisdom is good for this earthly life, it is the beginning of knowing God. Fearing Him is the only way to true wisdom, according to Proverbs 9:10 WEB "The fear of Yahweh is the beginning of wisdom. The knowledge of the Holy One is understanding."
We encourage these children to acknowledge God in all their ways, and He will make their paths straight, according to Proverbs 3:6 WEB 'in all your ways acknowledge him, and he will make your paths straight.'
Lastly, we remind those who are reading this prayer that just as we prayed for wisdom and success for these children, we must also pray for their salvation. In addition, we should pray that they will not be conformed to this world but will be transformed by the renewing of their mind as per Romans 12:2 WEB 'Don’t be conformed to this world, but be transformed by the renewing of your mind, so that you may prove what is the good, well-pleasing, and perfect will of God.'
