Philippians 1:3-6 “I thank my God in all my remembrance of you, always offering prayer with joy in my every prayer for you all, in view of your participation in the gospel from the first day until now.” (New American Standard Bible)
We have been at GOC since 2002 and have seen the people in the group change many times due to the nature of college ministry. Even though the particular people have changed the spiritual life has not. Thanking God is appropriate, because only He can provide such a work of grace throughout the years.
