After Abraham’s death his enemies came and plugged up his wells to ruin them for any future use. They threw sand, rocks, old wood, dead animal carcasses and garbage into the holes… filling them up completely and leaving them inoperable. And it says that it wasn’t until Isaac reopened them that the water flowed again. What’s interesting in this verse is the word ‘reopened’ which has a two-fold meaning…it means to rediscover and to re-dig. The enemy continues even today to try and plug-up our wells…not with sand and rocks, but with compromise, sinful habits, and worldly thinking. As Jesus told the Samaritan woman at the well in John 4:10, ” If you knew the gift of God and who it is that asks you for a drink, you would have asked Him and He would have given you living water.” Wells are necessary for the basic sustenance of life – water. But when your well has been stopped up, the water can no longer flow and you become a barren, dry desert.
