The past is behind us. Though we still remember it, there is nothing that we can do about the past, besides accept it and learn from it. If we dwell in regrets about it, we allow our life force and spirit to be hampered from learning, growing, and doing better in our present.
The present is our proving ground. This is the only time and place where we are tested and allowed to learn from history and God, to see whom we choose to emulate, and what we decide to put into practice.
We glimpse the future by faith in what we choose to believe. The future is filled with all sorts of promises, both of man and God. The test of our spirit and character is whether we opt to put our trust in the limited view and opinions of humanity, or in the infallible promises that the One Omniscient God has given us in His Word. Human opinions about the future conflict with one another, depending on the religions and philosophies of the individuals discussing the topic.
On the other hand, to quote Adoniron Judson, famous Malden, Massachusetts missionary to Burma: "The future is as bright as the promises of God." Here is the first step on the path to accepting and receiving the promises of God for your own life. By the way, God's promises are always good.
