2 Timothy 1:6
Wherefore I put the in remembrance that thou stir up the gift of God, which is in thee by the putting on of my hands .

The power of God came into your life the day you received the Holy Spirit:

Acts 1:8
“But ye shall receive power, after that the Holy Ghost is come upon you…”.

However, this doesn’t mean that the power is active all the time; you’ve got to activate it. That’s why Paul told Timothy to stir up the gift of God in him. He was referring to the power of the Holy Spirit which can be dormant in your spirit unless you activate it.

Sad to say that some folks have allowed that power lie dormant in them for so long. So, often times, you find them praying to God for what already belongs to them. The Lord, through His Word, shows us that we’re responsible for activating His power in us. Paul didn’t say to Timothy “Pray to God to stir up the gift in you,” for it’s not God’s responsibility, but Timothy’s.

When you pray in tongues you stir up the power of God resident in your spirit. Suddenly, that power that was quietly nestling in your spirit is activated and causes a change: you’re infused with divine strength, and the glory of God is revealed through you. It’s no use praying to God to send more power down from heaven. The anointing is in you already, but you have to activate it and put it to work. The way to activate the power of God in you is by speaking in other tongues! You can turn the power on whenever you choose, wherever you are – by speaking fervently in other tongues. So stir up that power right now; speak in other tongues.

2 Timothy 1:6 AMP
That is why I would remind you to stir up (rekindle the embers of, fan the flame of, and keep burning) the [gracious] gift of God, [the inner fire] that is in you by means of the laying on of my hands [with those of the elders at your ordination].

1 Timothy 4:14 AMP
Do not neglect the gift which is in you, [that special inward endowment] which was directly imparted to you [by the Holy Spirit] by prophetic utterance when the elders laid their hands upon you [at your ordination].
