Tim is a covenant child and a Peachtree City native. He is married to Rosie. They lived in Colorado the first 2 years of marriage, where Rosie taught High School, and Tim was employed by Natural Balance, Inc., as a Territory Manager. That is when he began attending seminary at New Geneva in Colorado Springs. During that time, Tim helped lead the youth ministry at Redeemer PCA in Parker. After two years, the Gwins were transferred back to Atlanta. Tim transferred to Reformed Theological Seminary and graduated from the Orlando campus in May 2006 with a Master of Divinity. Tim has completed two-thirds of the course work for a Master of Theology with an emphasis in Reformation Theology and should graduate in 2008.


For almost 7 years, Tim has been teaching and leading the college ministry at Carriage Lane.  In that time, he has taught a complete series on Systematic Theology; a series on Paul's Epistles; a series on Desiring God; selected passages in the Gospels, and a series on Evangelism and Apologetics. In March of 2006, he started leading the men's Bible Study and fellowship. Since then, Tim has taught through Philippians and 1 & 2 Thessalonians, Jonah, and Acts. The current study is in Paul’s letter to the Romans. Before the Men's Bible Study and fellowship on Wednesday evening, he leads a time of corporate prayer for the people and ministries of Carriage Lane. Tim also helps lead and teach the Good News Bible Club at Huddleston Elementary, which he attended himself in fourth through sixth grade. Tim has also helped lead foreign mission trips to Peru. His greatest joy and privilege is to preach and teach the Word of God.
