When was the fountain opened according to Scripture?

The opening of the fountain is primarily linked to the sacrificial death of Jesus Christ, which is the culmination of God's redemptive plan. This opening occurred historically at Calvary, where Jesus bore the sins of His people, fulfilling the prophecies foretold in the Old Testament. However, it is also significant to recognize that the fountain was opened in the mind of God from eternity, as Acts 2:23 affirms that His predetermined plan included the suffering of Christ to make salvation possible. Therefore, while its historical opening took place during the crucifixion, its spiritual implications reach back to God's eternal decree and will to save a specific people.
