The source of Christian assurance is God Himself

17 So the Lord said to Moses, “I will also do this thing that you have spoken; for you have found grace in My sight, and I know you by name.” 18 And he said, “Please, show me Your glory.” 19 Then He said, “I will make all My goodness pass before you, and I will proclaim the name of the Lord before you. I will be gracious to whom I will be gracious, and I will have compassion on whom I will have compassion.” 20 But He said, “You cannot see My face; for no man shall see Me, and live.” 21 And the Lord said, “Here is a place by Me, and you shall stand on the rock. 22 So it shall be, while My glory passes by, that I will put you in the cleft of the rock, and will cover you with My hand while I pass by. 23 Then I will take away My hand, and you shall see My back; but My face shall not be seen.” Exodus 33:17-23 (NKJV)

The passage above takes place after Israel’s idolatry with the golden calf (Exodus 32). Moses is seeking assurance from God that He would not utterly destroy Israel but would go with the people and remain with them to continue to make them a set apart people from other nations (Exodus 33:12-16). God did assure Moses that He would not abandon them, but then Moses made this remarkable request of God–he asked to see His divine glory in vv17–18. View article →
