Activating the power of God and getting yourself stirred in the Holy Ghost is important for every Christian. Acts 1:8 says, "But ye shall receive power, after that the Holy Ghost is come upon you..."; meaning that everyone who's born again and has received the Holy Spirit has received power. Though the power is in you, it may not be active on its own.
The one who wants to receive from God must activate the power of God for himself or herself through faith. Paul told Timothy to stir up the gift of God in him (2 Timothy 1:6), he was referring to the power of the Holy Spirit, which can be dormant in your spirit unless you activate it.
You're responsible for activating His power in you. When you pray in tongues, you stir up that power. Another way to experience the release of the power of God in your life is by declaring God's Word. For example, when you declare, "I can do all things through Christ which strengthens me"; "I'm the righteousness of God in Christ Jesus"; "The Lord is the strength of my life"; it won't be long before you're filled with the Spirit.
You can turn the power on whenever you choose —whenever you are— by speaking in tongues, and declaring the Word with boldness. Stir up that power right now; declare the Word with faith, speaking in tongues as well. Before long, your spirit will be activated and the glory of God will be revealed through you.
