The Atonement and Unity

Often unity in the trinity is argued by high-Calvinists in an attempt to demonstrate that their view of strict limited atonement is correct. But consider this:
    
   
In terms of sufficiency
     
God wills all to be saved by his will of disposition & will of precept (2 Pe. 3:9)
Christ's sacrifice is for the sin of the world (Jn. 1:29)
There is a general call of the gospel (Matt. 22:14)
    
    
In terms of efficiency
    
God wills that the elect be saved by his will of decree (Acts 13:48)
Christ intended to save His people by his sacrifice (Matt. 1:21)
The Holy Spirit calls the elect inwardly (2 Cor. 4:6)
    
    
Both are taught in scripture. Among each there is agreement, harmony, unity, and theological consistency. Nor does the one argue against the other.
    
The Arminian looks at sufficiency and ignores efficiency. 
    
The high-Calvinist's strict limited atonement view introduces theological inconsistency in the sufficiency side. It introduces inconsistency between the atonement and the genuine offer and God's revealed will that all be saved.
