Matthew 26:49 Immediately he went up to Jesus and said, “Greetings, Rabbi!” and kissed Him.
If you were going to betray someone, how would you go about it? Yes, I gather it is an unfair question based on what is going on, but think about why…
In order to win trust or respect we choose to do things in particular ways. If we want to get someone to trust us, then we do something in a way which will help them to trust us.
Here, Christ knew what was coming and He knew how He would be betrayed. Yet He still chose to go through with it and He also made sure everyone else was safe.
Christ said we need to love others – that love should not come with strings attached; just plain Christian love!
