This is the resurrection of life. It is the resurrection of the living.
What is the basis of salvation taught in this verse? If you read it in isolation from all that has gone before, it could mislead you. You could look at it and say, this sounds very much to me like salvation by works. But it is quite obvious that that is not what is meant because of the verses that precede it. Verse 25 says, ‘The hour is coming, and now is, when the dead shall hear the voice of the Son of God: and they that hear [and understand and believe] shall live.’ They have true faith in their hearts, a lively faith that shows itself by the good works it produces. They will be the ones who experience the resurrection of life.
