As a believer, you can know Christ within you. When you receive Jesus Christ by faith, you have new life within you, the life of Christ. You can sincerely say, "Christ lives in me, and the life which I now live in the flesh I live by faith of the Son of God, who loved me and gave Himself for me" (Galatians 2:20)
How can you know Christ within you? He lives within you through the Holy Spirit, also known as the Spirit of Christ. His presence is experienced through faith, hope, and love. These are the three abiding gifts of the Holy Spirit. "And now abide faith, hope, love, these three; but the greatest of these is love" (1 Corinthians 13:13).
How does the Spirit of Christ live in you through these three abiding gifts? Faith is within your heart to trust Christ as your living Lord and Savior. Hope is given for you to trust Christ with your future. Most importantly, the love of Christ is within you. The love of Christ enables you to love God and others.
Yes, you can know Christ within you. You know Christ within you by faith. You have Christ within you by hope that the world didn't give you, and the world can't take it away. You have the love of Christ within you, bringing peace and joy. This is the three-fold witness that Christ is within you, through faith, hope, and love.
