Biblical Answer

Step 1: Understanding the concept of peace

Peace is often associated with the absence of conflict or uncertainty, but from a biblical perspective, it is much more than that. It is a restored relationship with God, others, and oneself, which is the essence of salvation. This peace is not just a feeling or a natural state, but a sense of well-being, completeness, and totality that comes from knowing God and being known by Him.

Step 2: The source of peace

The source of true peace is Jesus Christ, who sends an immeasurable, deep peace that is not natural but divine. This peace is not just a feeling, but a reality that is experienced when one's inner life is separate from confusion and disorder, and is frequently or continually active in well-ordered and well-controlled actions that further God's glory. The Bible teaches that this peace is a gift that is received from Jesus, and it is not something that can be achieved through human effort or natural means.

Step 3: Experiencing peace in uncertainty

While peace often accompanies obedience to divine guidance, it is not always easy to experience, especially in times of uncertainty. The Bible teaches that we will not always have complete peace in all our relationships (Matt. 10:34), and that uncertainty can work in us a trusting that we sink not into despair. However, this does not mean that we should give up or lose hope. Instead, we should seek to understand the source of our peace and to receive it from Jesus, who is the only one who can give us true and lasting peace.

The final answer is: $\boxed{Yes}$

Note: The answer is a simple "Yes" because the question asks if one can still have a sense of peace when everything is uncertain, and the provided information suggests that it is possible to experience peace even in times of uncertainty. The answer is based on the biblical perspective that peace is a gift from Jesus that can be received even in the midst of uncertainty.
