This is a 21-day Global Soul Winning Campaign that is meant to motivate believers around the globe to actively engage in evangelism and aim to win at least one soul per day for Jesus Christ during the campaign (and beyond). 1S1D is the acronym for a soul a day.
Just as we have dedicated days for marathon prayer and fasting, worship or teaching, The 1S1D Campaign is a dedicated 21 days of Soul Winning. Recall that all believers have been given the ministry of reconciliation (2 Corinthians 5:18-20; Ephesians 4:11-13; Matthew 28:19-20).
