1 Timothy 4:9-10
Faithful is the word (logos) and deserving of full acceptance. This is why we labor and strive, because we have set our hope on the living God, who is the Savior of all people, especially of believers.
Especially of believers: whom He saves with eternal salvation, yet of temporal salvation are the words to be undetstood. As there is a general Providence which attends all mankind, there is a special one that relates to the elect of God who are especially saved and preserved before conversion, in order to be called, and after conversion, after they are brought to believe in Christ, are preserved from many enemies and are delivered out of many afflictions and temptations and are the peculiar care and darlings of Providence, being to God as the apple of His eye. If He is the Savior of all men, then much more of them who are of more worth, value and esteem with Him than all the world, and if they are saved by Him with the greater salvation, then much more with the less. If He is the common Savior of all men, especially of saints, whom He saves both ways, then there is great reason to trust in Him for the fulfillment of the promises of life, temporal and eternal, made to godliness and godly persons. This epithet of God seems to be taken out of Psalm 17:7 where He is called the Savior of them that trust, or believe.
