And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ. Faithful is he that calleth you, who also will do it. - 1Th 5:2324 KJV
You might consider Paul's words in 1 Thessalonians 5 the crossroads between theological knowledge and personal comfort. Divine Preservation, the concept that God will preserve His elect blameless, is a theological truth which gives us such great assurance that no matter what this world holds for us, God will have the final victory in our behalf.
