40-Day Impact Challenge
The Forty Day Impact Challenge is a call for individuals to set aside a period of 40 days to press into the Lord and seek His will for their lives. Supported by friends and family, Christ-followers throughout the nations will dedicate themselves to prayer, fasting, and the reading of scripture in order to discover their kingdom purpose and equip themselves for this labor.
The Forty Day Impact Challenge occurs annually with the next occurrence beginning across the globe on January 19, 2015 and lasting until February 27, 2015.
This challenge is open to people of all ages, but is particularly helpful for those who are seeking their unique ministry calling. Family members, dating or married couples, and small group members are especially encouraged to participate in the challenge together and to agree on specific challenges to complete as a group.
Churches, fellowships, campus groups, and families are encouraged to take advantage of the resources offered on this site to promote the Challenge among their members and to properly prepare for the Challenge prior to the start date.
