By asking the Lord for the baptism, you have made yourself available to Him unconditionally in this area so that whatever He wants for you, you have acknowledged His right and authority to give it to you, in His manner and timing. Whether you sense a change at that moment or not is not relevant to the asking, though you can be assured that He will in some way acknowledge the asking by responding. So be aware, expectant and ready to respond with stillness, gratitude and rest. This doesn’t mean you will have a specific experience mentioned in scriptures. For instance, you may or may not experience speaking with other tongues, audible sounds of rushing wind, physical manifestations of fire, or the ability to preach in other languages! We know God is faithful, and in time and in His way will make Himself known. He doesn’t want us to be drawn to the baptism, He wants us to be drawn to Him.
