We used to go before the Lord to seek His face concerning who to marry! Often, with fasting, patience, and waiting on God to give a definite instruction.
Today, people mostly simply choose who they want and then pray to God to approve their choice. People decide who they want by simply checking social media profiles and drawing conclusions from there.
I believe strongly that God wants to lead us and guide us and has preferences for us. We can find this in the place of prayer and seeking His face.
Most people have been married under the permissive will of God. When people insist on who they want before God, they mostly always end in His permissive will. However, the ultimate plan of God is that we get married under the perfect will of God.
