Spiritual health
Above the health status of your body there is a spiritualself examination to know thy standing in the kingdom ,the litmus test to know if the health of your spirit is strong is your prayer life ,any thing that affect your prayer life is worse than cancer or covid-19.
A prayerless Christian is a weak and sickling Christian ,a prey for darkness to feast upon.
Nothing on this Earth should be allow to affect and attack your prayer life ,if you lost communication with your creator death come quickly.
