The realm of God’s open hands speaks of frequency of permanent satisfaction.
The rain speaks of plenty & abundance which depicts the expression of divine visitation.
Its a seal of remembrance, the proof of divine involvement on mortal matters and a sign of kingdom predominance.
Rain is divine judgment on wickedness and preserve the saint. Until wickedness is judge it continues. No matter how nice you are, this world is wicked so prepare yourself to know how to challenge it and stop it.
Rain is a proof of new beginning. Every divine agenda needs a man. Without man God will not , without God man cannot.
Nothing triggers the rain like supernatural grace that is the involvement of God in the affairs of men.
