I love it when the Holy Spirit leads me to His divine appointments and I see how God has been working in lives before He leads me to them to share the Gospel with them. Then to see them ask Jesus to take their sins away, and come into their lives to guide them into all truth. 
I know I will see them in eternity. We will be with Jesus forever in His Kingdom as He promised. This is the greatest and most important thing in all lives. This life passes quickly then we go into the real life, life eternally. Each person has a divine choose, Chose to believe Jesus or chose to reject Him. Jesus said anyone who believes in me has everlasting life. He also said God so loved the world that He gave His only begotten Son, and whosoever believes in Him has everlasting life. 
We just have to trust in what Jesus said, trust in Him and Him alone for eternal life. https://app.backtothebible.org/en/messages/66053?orgid=399 via @Beyond Sundays
