Intensive Programs of Growth (IPGs) are systematic campaigns to teach the Bahá'í Faith through cycles of expansion, consolidation, reflection and planning. They aim to accelerate the process of people embracing the Faith "by troops" as prophesied. IPGs involve intense teaching efforts through campaigns, home visits and firesides to invite many people to learn about the Faith over short periods, followed by nurturing seekers' spiritual development. The friends are urged to devote their energies to establishing 1,500 IPGs worldwide by 2021 to advance this process of mass enrollment in the Faith.
