That God disguises his plans for you is by design, not mistake.

In the absence of faith uncertainty can cause us to collapse into fear or cynicism.

To contend with this God disguises his plans because if they were fully visible, faith would become unnecessary.

By demanding that we employ trust, patience, and reliance on something greater than ourselves, uncertainty is then a prerequisite to, or the primary condition for, faith.

Once faith is established, and we act with trust and patience, only then can his plans come to fruition.

Uncertainty is then the weight with which we train the muscle of faith. Faith is the practice of deepening trust and abandoning fear. Right actions then follow.
