Charles Spurgeon Commentary 2 Corinthians 4:13-14

"But having the same spirit of faith, according to that which is written, I believed, and therefore did I speak; we also believe, and therefore also we speak; knowing that he that raised up the Lord Jesus shall raise up us also with Jesus, and shall present us with you." — 2 Corinthians 4:13-14 (ASV)

We having the same spirit of faith, according as it is written, I believed, and therefore have I spoken; we also believe, and therefore speak; knowing that he which raised up the Lord Jesus shall raise up us also by Jesus, and shall present us with you.

Note the assurance of apostolic preaching and writing. There is no "if" here, no hesitation, no doubt. The apostles knew what they believed, and knew why they believed it, and they spoke with the accent of conviction; nobody was led into doubt by their hesitancy.
