Mark 8:18 Having eyes, do you not see? And having ears, do you not hear? And do you not remember?
When Jesus began to warn the disciples about the leaven of the Pharisees, they thought he was talking about bread. They thought he was saying these things because they had forgotten to bring bread with them. Jesus had just multiplied bread and fish for the second time right before the disciples got into the boat to cross over. Already they are concerned about a lack of bread.
How many times has God intervened in your life in a supernatural way where He’s done something really miraculous for you, solved a problem or answered a question or brought provision? In that moment we believe that we will never forget what God has done for us and that this will be such a boost to our faith for all time. But usually within just a matter of days we have forgotten and we are again fretting and complaining and wondering if God will come through.
Mark 8:21 So He said to them, “How is it you do not understand?”
The word understand is “syniemi” and it means put together, i.e. join facts into a comprehensive inter-locking whole
We might say it this way, that it’s putting two and two together. They had been with Jesus when there was a need for food for the multitude and He provided it. Then on another occasion there was a need for food for the multitude and He provided it. Times without number there were people who needed healing and deliverance and He provided it. Putting two and two together means we recognize that whatever our need is we have a Savior who is able to meet it. We need fear no lack, no problem. We just need to remember the testimony of God that we have already experienced in our lives, knowing that He is the same God today.
He wants us to remember that time we were sick and we went to the doctor, then to the medicine cabinet, and found no relief. Then we went to Him and He healed us.
He wants us to remember the time our heart was broken and we went to our best friend and we went to our mom, and found no relief. Then we went to Him and He comforted us.
He wants us to remember the time we fell into sin and devastated our life and had nowhere else to go. So we went to Him and He forgave us and restored us.
So often I have a tendency to live my life as a series of disconnected events. But He is writing a story and building a testimony into my life and every piece along the way is an important part of the whole. When all the pieces come together they make a beautiful picture of the work of God in us.
He is my Delight 
Boy am I guilty of this: forgetting how God has helped me in the past. Perhaps our Iives with God are like a big parade—we can only see what is going past us, but God sees everything. Blessings.
I think we are all guilty of this. We would spare of lives a lot of worry and fear if we remembered the testimony of God’s working in our lives.
God bless your day!
