We searched for "In His Grace" together with Clanwilliam, for the given domain inhisgrace.co.za, and for the name on Facebook, and we found nothing at all that links this church name to Clanwilliam or to South Africa. The only "In His Grace" bodies that surfaced are in the United States, namely In His Grace Community Church in Kenockee, Michigan (inhisgracecc.org) and two American Facebook pages, In His Grace Ministries Inc, a non-denominational ministry page, and a small page called "In His Grace" aimed at women's ministry. Searches about Clanwilliam itself returned only long-established congregations there, such as the Anglican and Dutch Reformed churches (Wikipedia heritage and denomination listings), with no mention of this group. The findings are summarized here for space; the full research was weighed in the review.
Our conclusion: Our server successfully opened the given website, https://www.inhisgrace.co.za, and it carries the title "In His Grace | Grace that transforms" with bilingual English and Afrikaans wording ("'n Plek om in genade, geloof en roeping te groei") plus South African ministry features such as Veldskool, devotions, discipleship and Restore360, which matches both the submitted church name and a South African setting. The contact email, info@inhisgrace.co.
No further action is needed. This report is refreshed whenever the church is reviewed again.
