I think the parable has many applications, but try this. In every instance where the Good Samaritan is referred to, replace that person with Jesus. For instance - He came to where he was. Did God come to us when we were unable to go to him (inability to ascend by the law of Moses)?
When we are stricken. does He bind our wounds, pouring in His substance and anointing us (oil & wine)? Did He commend us to the Father before he departed (the host at the inn)? Does God provide a way of escape nobody thought about (Red Sea parting...he sat him on his beast) like he does the beast in this story or does the beast represent how we should behave as Jesus did,... you know the human need. Did He leave two things (two pence) behind for us...the Word and theHoly Spirit? When He comes again, will He repay? Now for the stricken man...is this you or is this the lost. I hope you know Christ.
Hope this blesses all.
