It is a good and needful prayer you have offered, to ask the Lord for wisdom and understanding and to be guided by His will. The Scriptures teach us that the heart which truly seeks is already being drawn by grace, for salvation and all spiritual light are of God's will, and the work of the Spirit is to change the human will and make men willing in the day of God's power.
You ask that revelation and guidance be given to you now. Know then where that light is to be found. Believe this Book from the first word of Genesis to the last line of Revelation, for it will never mislead you. There is a revealed will of God which we must not violate, and it is plainly set before us in His Word. There is also a providential will of God which we should always consult, as He orders our circumstances and opens and shuts doors according to His wise plan. All things are under regulation and have an appointed place in God's purpose, and nothing happens but what He permits or ordains.
Therefore continue to pray, and pray earnestly, for God has said, Ask and you shall receive. Yet pray also with holy resignation after your Saviour's perfect model in the garden, Nevertheless not as I will, but as Thou wilt. You do not know what God's will is in every particular of the future, and it is foolish for any man to say, I will go and do this or that, as if he could both propose and dispose without asking God's consent. Rather say, and feel in your heart, If the Lord will, I will do this or that. In this you will find three firm grounds of confidence, God's sovereignty, Christ's sacrifice, and God's immutability, for He abides the same forever.
If you would have more understanding, seek first the kingdom of God and His righteousness, and give yourself to His Word and to prayer. A prayer will reach Him, a wish will find Him, a groan will pierce His heart. Trust not in sudden notions or fancies apart from Scripture, but ask the Holy Spirit to open your eyes to what is already written, and to make His way plain to you step by step.
Let us pray together for you now. O Father of lights, with whom is no variableness, we ask in the name of Jesus Christ Thy Son that Thou wouldst grant to this seeking soul a clear sight of Thy will. Give understanding of Thy Word, make the heart willing to obey what Thou hast revealed, and order the steps by Thy providence. Grant wisdom liberally to them that ask in faith, keep them from fainting, and cause them to see Thy goodness even now and here. Let Thy grace be with them, and lead them to rest not in seeking only, but in finding Christ, in whom are hid all treasures of wisdom. We ask this in the precious name of Jesus, Amen.
