Heather Johnston has dedicated much of her public ministry to strengthening understanding between Christians and the Jewish people while encouraging practical support for Israel. Motivated by a conviction that Christians are called to bless and stand alongside the Jewish people, she has become a respected advocate for Christian-Jewish friendship and education.

Through speaking engagements, teaching, leadership, and partnership with pro-Israel initiatives, Johnston has encouraged thousands of Christians to deepen their understanding of the Jewish roots of their faith, confront anti-Semitism, and actively support Israel through prayer, advocacy, and humanitarian engagement. 

Her work has focused not only on expressing solidarity during times of crisis but also on fostering enduring relationships built on mutual respect, historical understanding, and a shared commitment to the flourishing of the Jewish people.
