As a Christian you have all the power you need for all the problems you face. The Bible says your body is a temple for the Holy Spirit who is in you. The question isn’t, “How do I get more of the Spirit?” but rather, “How can you, Spirit, have more of me?” We’d expect a Mother Teresa-size answer! Build an orphanage. Memorize Leviticus. Bathe lepers. Do this and be filled, we think. Do this on your own and be tired, God corrects.
Do you desire God’s Spirit? Here’s what you do: He says everyone who asks will receive. You know how to give good things to your children; how much more your heavenly Father will give the Holy Spirit to those who ask him. Friend, you can do all things through Christ who gives you strength. Welcome the Spirit into every part of your heart!
