“And Abraham planted a grove in Beersheba, and called there on the name of the LORD, the everlasting God.” Genesis 21:33
When people use the term forever, as in, “our love will last forever,” they may be sincere, but they have no power to bring it to pass. Only God can accomplish everything He says, and throughout eternity; unlike us God is eternal.
God made a promise to Abraham that He would be the Father of a nation; Sarah and Abraham failed to bring that promise to pass on their own by making Hagar the mother of Abraham’s child. Then, God fulfilled His own word in Genesis 21 by visiting Sarah in her old age and giving her an offspring.
At that same time, we read of a covenant that took place between Abraham and Abimelech over a well that Abraham dug, and seven lambs that Abraham gave to Abimelech as a sign that Abraham had dug the well. Abraham knew how men make promises and then break them, but now Abraham was becoming fully conscious that God never breaks His.
The following phrase is very meaningful in the scriptures, ‘Abraham called upon the name of the LORD,’ these are not arbitrary words but signify that the one calling understand who and what God is with regards to that name.
The Christian understands that unlike man, time is the servant of God; He is the master of all things, and when He makes a promise, He has the power to keep it.
