"For you have forgotten the God of your salvation and have not remembered the Rock of your refuge; therefore, though you plant pleasant plants and sow the vine-branch of a stranger, though you make them grow on the day that you plant them, and make them blossom in the morning that you sow, yet the harvest will flee away in a day of grief and incurable pain." - Isaiah 17:10–11
There was a time when I just forgot because I had too much on my mind, but now I just plain forget. Whether it be a busy schedule or age, forgetfulness can be controlled. That's why calendars, little note pads and note apps are made. We can keep track in many ways, but in the end we only remember what we want to remember.
In the midst of divine judgments of various nations, the Lord returned to focus on his people. He was the God of their salvation and the Rock of their refuge. But, they forgot his blessings and place in their life and worship. They went about their daily routine hoping for a full harvest, but only grief and pain came. Why? Because they only remembered what they wanted to remember.
Let's be honest with ourselves... Some forgetfulness isn't because of stress or age, it's simply a matter of choice. Then, when we begin to experience sad and disappointing results, we wonder why. Jesus made it very clear when he said in John 15:5... "I am the vine; you are the branches. Whoever abides in me and I in him, he it is that bears much fruit, for apart from me you can do nothing." Be wise and "want" to remember the Lord... and then remember.
