God: "I looked for someone to take a stand for me, and stand in the gap" (Ezekiel 22:30)
It helps me to think of it this way. As a Christian, there are three stages of our salvation. In the past, we were saved from sin’s penalty. In the present, we are saved from sin’s power. And in the future, we will be saved from sin’s presence. Or, in the past – justification. In the present – sanctification. In the future – glorification. Or, we have been saved. We are being saved. And we will be saved.
Thankfulness to God is a recognition that God in His goodness and faithfulness has provided for us and cared for us, both physically and spiritually. It is a recognition that we are totally dependent upon Him; that all that we are and have comes from God.
