What should believers constantly remember about our love for Jesus versus His love for us?
Believers must constantly remember that the focus is not how much they love Jesus, but how much He loved them. He saved them and keeps them. This is pictured in Lazarus's account, where people marveled at His love for Mary and Martha, not their love for Him.
Les explains from John chapter 11 that the account of Lazarus makes this clear: all through the chapter it was not how much Mary and Martha loved Jesus, but how much He loved them. When Jesus wept, the Jews said, 'Look how He loved them,' not how much they loved Him. Les says this is something we have to constantly remember: it isn't how much we love Him, it's how much He loved us, and has saved us, and has kept us. Paul then says, with that in view, 'I do not frustrate the grace of God.' Les notes that not many understand the grace of God; people imagine God is waiting for frail humans to goof up so He can zap them, but God's attitude is one of total love, mercy, and grace. He also points to the carnal Corinthians, who had many problems, yet Paul still writes to them.
