6So when they had come together, they asked him, ‘Lord, is this the time when you will restore the kingdom to Israel?’ 7He replied, ‘It is not for you to know the times or periods that the Father has set by his own authority. 8But you will receive power when the Holy Spirit has come upon you; and you will be my witnesses in Jerusalem, in all Judea and Samaria, and to the ends of the earth.’ 
Acts 1:6-8

26A new heart I will give you, and a new spirit I will put within you; and I will remove from your body the heart of stone and give you a heart of flesh. 27I will put my spirit within you, and make you follow my statutes and be careful to observe my ordinances. 
Ezekiel 36:26-27
