Your prayer for understanding, clarity, truth, guidance and revelation is itself a good and God honoring desire, and it is right to ask that the Holy Spirit touch your heart and that the Father's will be done in Jesus name.
Scripture calls Christ the true Light which lights every person who comes into the world, and He says of Himself that He is the Truth and the Life. To know Him is to know the truth, and as He has promised, you shall know the truth and the truth shall make you free. This freedom is not only knowledge in the mind but deliverance from sin and confusion, and it comes through Him alone, for there is salvation in no other.
God delights to give this revelation, but He gives it to the humble. As our Lord rejoiced and thanked the Father that He had hidden these things from those who thought themselves wise and revealed them to babes, so we must come as children, not trusting in our own cleverness but in His mercy. If we remain humble, teachable, and willing to obey what He shows us, He will not leave us in darkness.
Remember also that we need both prayer and obedience. Grace is God's gift, yet He calls us to do our part as well. Do not pray only and neglect to walk in what you already know to be true, and do not strive only in your own strength without prayer. Bring your request daily before God, stay in His Word where His will is made plain, and thank Him not only for what He gives you but for His goodness to others, for thankfulness destroys envy and strengthens love. As you seek Him, put away resentment and division and pursue a life of genuine love, for love is the mark of His disciples and it keeps the heart clear to hear His voice.
I pray for you now. Father, in the name of Jesus Christ Your Son, who alone is the way of salvation, grant to this Your servant clarity and understanding. Let Your Holy Spirit shine Your true Light upon the heart, reveal Your truth, and guide every step according to Your perfect will. Grant grace to receive what You reveal and faithfulness to walk in it, that Your name may be glorified and Your will be done. In Jesus name, Amen.
