Charles Spurgeon Commentary 2 Timothy 2:10

"Therefore I endure all things for the elect`s sake, that they also may obtain the salvation which is in Christ Jesus with eternal glory." — 2 Timothy 2:10 (ASV)

Therefore I endure all things for the elect's sakes, that they may also obtain the salvation which is in Christ Jesus with eternal glory.

Not that the sufferings of Paul had anything meritoriously to do with the salvation of the elect, but that by his earnest strivings and sufferings the word of the gospel was brought to their hearing; faith then came by hearing, and so they were saved.
