In an ideal world we would have clarity before we make decisions. But we do not live in an ideal world. Still we have to make minor and major decisions daily. To do this, God has gifted us with discernment and fidelity. We may not have clarity but we can have peace, trusting in God's guidance and love in the process. If after reflection and prayer we have peace about a particular decision, not absolute clarity then we can  move forward in this decision, while at the same time entrusting it to the Lord for final approval or disapproval. In making this discerned decision, we surrender it to God to open or close the door. The clarity of a right or wrong decision comes after prayer, discernment and action.
