O clavis David, et sceptrum domus Israël ; qui áperis, et nemo claudit ; claudis, et nemo áperit : veni, et educ vinctum de domo cárceris, sedéntem in ténebris, et umbra mortis.
O Key of David, and sceptre of the house of Israel; who openest, and none closeth; who closest and none openeth: Come and draw out the convict from the prison-house who sitteth in darkness and the shadow of Death.
The proverb says that some people are so lazy that they can't even put food into their own mouth, i.e. they won't even take steps to help themselves when the solution is right in front of them.
We cannot escape the fact that we are sinners. The Lord Jesus shows us very clearly that our love for Him is finite. There are always conditions on our love for Him. We often say with Meatloaf, "I'll do anything for Love, but I won't do that".
However in four days time, we are presented with a baby who will open the door for us to Heaven some thirty years later in His life with us. We have three choices. We can sit on our backsides in blissful ignorance of or blissful antipathy toward our need for God and then be surprised when He tells us He doesn't know us; we can recognise His love for us and sit on our backsides saying, "oh He'll sort it all out" and then wonder why our lamp goes out; or we can get up, walk towards Him, fall over, scuff our knees, pick ourselves up and walk towards Him again and thus make progress to Him from our darkness as he stands at the open door in a blaze of Heavenly light.
