Is it true that all Christians love Jesus and he loves them?

A Christian is a person who is filled with the Spirit of Christ as Romans 8 (first half) explains. All those who belong to Christ by faith love Him because they discovered that He first loved them and died for them, even before they were born (John 3:16 & 17:20-23).

However, there are very many people who claim to be Christians but who do not love Jesus, otherwise they would be obedient to His commands (including living a moral life, following Him even though that means disowning self and taking up their cross daily). That's going by outward demonstrations of whether a person's claim is sound, or not. We can make mistakes there and it's not our place to judge individuals, but it is unarguable that many will glibly spout the words, "Oh, I love Jesus!" but their lives seem to be a virtual denial of that. Yet still Jesus loves sinners and they can be cleansed from their sins if they trust in what Jesus did - in love - to deliver them.

All that believe, follow, hear Jesus, yes. We need more Agape one for another, interested in one another.
