Was Jesus' death an accident or an unplanned stopgap by God?

Les explains that Christ's death was not a sudden act of God as a stopgap, nor was it an accidental martyr's death. Instead, it was all in the pre-eternal mind of God, so that everything would fall into place. Paul delivered what he also received: that Christ died for our sins according to the Scriptures, was buried, and rose again the third day according to the Scriptures. The gospel is not based on Judaistic law, nor merely on Christ being Israel's Messiah, but on the Messiah of Israel, the Son of God, dying on the Roman cross, shedding His blood, being buried, and rising again. He was really dead, then seen by Peter and over 500, and Paul also saw Him alive.
