In the second aliyah the Torah explicitly says that after we experience the blessings and the curses and find ourselves in exile scattered among the nations (as we are now), we will wholeheartedly return to G-d, and G-d will gather us from the furthest reaches of the heavens and bring us back to the land of Israel to live (may this happen speedily in our days). Rashi says that G-d Himself will return with us because He is in exile with us, and that G-d will individually take each person by the hand and redeem them. Then, at the end of the aliyah it says that G-d will remove the barrier to our hearts so that we will love Him.
