Jesus emitted a groan and said: " 'Ephphatha!' (that is, 'Be opened!')" (Mk 7:34) Through this prayer, Jesus opened the ears and mouth of "a deaf man who had a speech impediment" (Mk 7:32). But there are greater and grander openings than these.
At the end of the Old Testament, the Lord promised that when we obeyed Him by tithing, He would open for us "the floodgates of heaven, to pour down blessing upon [us] without measure" (Mal 3:10). But there are greater and grander openings.
The grandest opening is to open "the door of faith" (Acts 14:27), that is, to open our hardened hearts (see 2 Cor 6:13). In this way, the "door to heaven" is opened for us (Rv 4:1).
We speak of an open mind, open enrollment, open arteries, the open man, open bowling, open bar, etc. The word "open" is at the entrances of hundreds of thousands of businesses. Yet all these openings mean nothing unless we have hearts open to the Lord. If you open your heart when Jesus says "Ephphatha!", He will open the gates of heaven when you say: "Ephphatha!"
