How do we know the Gospel of Luke is true?

The truthfulness of the Gospel of Luke is grounded in its meticulous attention to detail and the authority of its sources. Luke claims to have 'perfect understanding' obtained through careful investigation of events as reported by those who were actual eyewitnesses and ministers of the word. This declaration indicates that Luke's account is not just a narrative but a well-researched historical document that reflects divine inspiration and accuracy. Furthermore, the Gospel is believed to have been written under the influence of the Holy Spirit, reinforcing the sovereignty of God's revelation through scripture. As a part of the New Testament, it contributes significantly to the overarching story of redemption that God's word communicates.
