89 The reason, unless I am mistaken, is complete and just, but I do not require a reason from Christ. If I am convinced by reason I reject faith. Abraham believed God, let us also believe Him, that we who are heirs of his race may also be heirs of his faith. David likewise believed, and therefore did he speak; let us also believe that we may be able to speak, knowing that “He Who raised up the Lord Jesus shall raise up us also with Jesus.” For God, Who never lies, promised this; the Truth promised this in His Gospel, when He said: “This is the will of Him that sent Me, that of all that which He has given Me I should lose nothing, but should raise it up at the last day.” And He thought it not sufficient to have said this once, but marked it by express repetition, for this follows: “For this is the will of My Father, Who sent Me, that every one that sees the Son and believes in Him should have eternal life, and I will raise him up at the last day.”
