Calvary Church Podcast featuring Mr. David Seidman

By the time a student graduates from high school in the United States, they will have spent approximately 18% of their life in class. So as believers, how do we take advantage of that time to train up mature leaders and followers of Christ? On this episode of the Calvary Life Podcast, Pastor Eric sits down with our own Mr. Seidman! Together, they discuss what makes Christian education “Christian”, the importance of having believers in secular schools, and the value of first-grader’s weddings.
