How do we know Jesus’ forsakenness is key to understanding the gospel?

The cry of Jesus from the cross, 'My God, my God, why have you forsaken me?' is pivotal in understanding the gospel narrative. This moment illustrates the weight of sin and its consequences. Jesus was forsaken so that His people would never experience abandonment by God. His sacrifice is the ultimate display of love, as He willingly faced the ramifications of sin. This underscores God's holiness and the seriousness of sin, portraying the necessity of Christ's substitutionary death for the redemption of believers.
