The national flag of Nigeria is made up of two colours (green and white) symbolising the Tree of Life and the River of Water of Life.
Green is the colour of the leaves of the tree of life, and white is the colour of the river of life. The River Niger is the river of life flowing down the middle of Nigeria; while the green vegetation on the left and the right sides of the River Niger is the tree of life.
Therefore the Nigerian national flag (Green-White-Green) is described in Revelelation 22:2 as follows:
And on either side of the river, was there the tree of life. (Revelation 22:2) "KJV"
White = the River
Green = the Tree of Life
Either side of the river: the left side and the right side of the white colour
On either side of the river, was there the tree of life: Green is on the left side and the right side of the white colour
Nigeria is the land of religious reconciliation - a grazing ground for the whole world. People from other nations of the world are invited to come and graze in Nigeria and become healed of religious conflicts.
And the leaves of the tree were for the healing of the nations. (Revelation 22:2) "KJV"
Green: the leaves of the tree
Healing = Reconciling
Healing the nations: reconciling the nations
And the leaves of the tree were for the healing of the nations: the green colour of the Nigerian national flag symbolises international peace and reconciliation.
White in the middle of the Nigerian flag is Holy Wisdom flowing like as the River Niger down the middle of Nigeria.
