Stated plan

March the king toward the kingside to support the pawns and challenge the bishop's control of the long diagonal.

Reasoning

The black bishop on d4 sits on the long a1–h8 diagonal, controlling both g7 and h8, so pushing g6-g7 or h5-h6 immediately fails to the bishop's diagonal coverage (Bxg7 still covers h8). White cannot push through immediately; instead the king must approach to challenge the bishop and support the pawns' advance. Kf3 is safe (not attacked by the e3 or c4 pawns nor the black king) and begins the march toward e4/f4/f5, eventually helping force the bishop away or trapping it while shepherding the pawns to promotion.
