What is the seal of the living God, which is
placed in the foreheads of His people? It is a mark
which angels, but not human eyes, can read;
for the destroying angel must see this mark of re-demption. The intelligent mind has seen the sign of
the cross of Calvary in the Lord’s adopted sons and
daughters. The sin of the transgression of the law of
God is taken away. They have on the wedding gar-ment, and are obedient and faithful to all God’s
commands

4 - The seal is an invisible mark of loyalty
and obedience to our Creator.
