Rom 8:11 And if the Spirit of him who raised Jesus from the dead is living in you, he who raised Christ from the dead will also give life to your mortal bodies because of his Spirit who lives in you.
This is the confidence you have. Jesus lives in you. The Spirit of God who rose Jesus from the dead dwells in you. Now this is a lot of power. This power is to love, to persevere, and to accomplish the will of God.
It is hard to imagine this kind of power. You may wish to raise the dead yourself, and you might, but for now, in the everyday, his power is sufficient to accomplish everything of the Spirit. It is without trumpets and cheering crowds but powerfully working as you yield.
There are days you feel powerless; yield! Many days you feel weak; give in to him! Sometimes you feel he should do more through you; have confidence as you submit to him and draw near that his working in you is perfect.
Dream and pray big but be content in his working in the now. Remind yourself that it is perfect and rest knowing this power resides in you and works through you. Be content with the Spirits working in you today.
