ISAAC (Genesis 25:19 to Genesis 27:46).
After the heart warming record of the obtaining of a suitable wife for Isaac as a result of the direct activity of Yahweh little is told us about him. This is because during his lifetime important covenants and theophanies were few and therefore there was no recording in writing.
The family tribe over which he presided continued to be strong (Genesis 26:16) and he clashed with Abimelech at Gerar but that is almost all we know about him apart from the birth of his children and his part in the continuation of the chosen line. But he did continue Abraham's policy of allying his family with the family of Abraham's father Terah and was upset when Esau departed from it (Genesis 28:9). More dangerously (and with less justification) he also continued the policy of describing his wife as his sister. He seems to be a mirror image of his father but without his effectiveness and personality.
But his importance is that he was part of the fulfilling of God's purposes. He was not charismatic, he was not outstanding, but he was chosen by God and was a necessary part of the chain that led up to Moses, then to David and finally to Jesus Christ. What Abraham began he had to hold on to and continue. And this he did, without fuss and without bravado. He was there when God wanted him.
We too may feel that we are not important, but if we are His and responsive to His words we too are an important part of the chain that leads to the fulfilling of His purposes. Isaac should be an encouragement to us all.
However, Isaac is seen later as an important member of those to whom the covenant was given (2Ki 13:23; 1 Chronicles 6:16; Psalms 105:9). In Amos 7:9; Amos 7:16 Isaac is used as another name to designate Israel.
