One of my favorite authors, Dallas Willard, writes something helpful here:
“…the crushing weight of the secular outlook… permeates or pressures every thought we have today. Sometimes it even forces those who self identify as Christian teachers to set aside Jesus’ plain statements about the reality and total relevance of the kingdom of God and replace them…The powerful though vague and unsubstantiated presumption is that something has been found out that renders a spiritual understanding of reality in the manner of Jesus simply foolish to those who are “ in the know.” But when it comes time to say exactly what it is that has been found out, nothing of substance is forthcoming.”—Dallas Willard (The Divine Conspiracy)
You need to know that there are strong reasons supporting the Christian faith: God’s word, changed lives, archeological and scientific discoveries, philosophical arguments, love, goodness, and the work of the Holy Spirit—just to name a few. Don’t worry, no one has found out that Christianity is false and you are the only one who still doesn’t know.
As Christians, we don’t need to walk around as if we are afraid we have something hanging out of our noses that everyone can see but us. You don’t have to check your brains at the door. Your mind and heart are both valued as a follower of Jesus (Luke 10:27). Let us pray that we would have the courage in this generation to contend for the faith delivered once for all and to always be ready to give an answer for the hope we have in Christ. Listen Paul’s challenge: “do not be ashamed to testify about our Lord, or ashamed of me his prisoner. But join with me in suffering for the gospel, by the power of God” (2 Timothy 1:8). God is real, Christianity is true and we have no reason to be ashamed.
