Jesus offered a complete sacrifice. When His blood flowed it was enough to deal with our sin – once and for all. When He said: “It is finished”, He meant it. Nothing can be added to His sacrifice – all judgement has been lifted off us if we believe in what He did. Therefore God is not angry at us! When He sees us He looks into the wonderful, complete sacrifice Jesus became.
“But as it now is, He has once for all at the consummation and close of the ages appeared to put away and abolish sin by His sacrifice [of Himself]…Even so it is that Christ, having been offered to take upon Himself and bear as a burden the sins of many once and once for all…” Heb 9:26, 28
“Whereas this One [Christ], after He had offered a single sacrifice for our sins [that shall avail] for all time, sat down at the right hand of God…For by a single offering He has forever completely cleansed and perfected those who are consecrated and made holy.” Heb 10:12, 14
Look at those words – “put away”, “abolish”, “once for all”, “a single sacrifice”, “for all time”, “forever”, “completely”, “perfected”, “made holy” – why do we try to appease God by striving to live holy? If we live in a relationship with Jesus this will come naturally – like bearing fruit, but it should never come from a fearful, condemned mindset. One sacrifice was enough forever, we cannot add to it or improve it.
