Heartline Pregnancy Center will host a prayer walk in honor of Sanctity of Life Sunday at 6 p.m. The prayer walk will be in the K21 Health Services Pavilion, 1515 Provident Drive, Warsaw. The event is free and open to the public. National Sanctity of Human Life Day was first introduced by President Ronald Reagan on Jan. 13, 1984, as a day to be recognized each year on Jan. 22 as it was the day the Supreme Court decided Roe v. Wade. In honor of this, Heartline Pregnancy Center will host the prayer walk to remember those who have lost their life to abortion and to remind the community about the importance of protecting human life from abortion.
