Though you have not seen him, you love him. Though you do not now see him, you believe in him and rejoice with joy that is inexpressible and filled with glory, obtaining the outcome of your faith, the salvation of your souls.
1 Peter 1:8-9
The apostles and those who lived while Jesus Christ walked here on the Earth had it made, they were able to see him and experience the things we read in God’s Word first hand. For us it takes faith. It is the Holy Spirit that speaks to our heart, the Bible (the inspired word of God), and His creation that speaks to His existence. He lives in us, we can rejoice!
