It says in Romans 5:5, “the love of God is shed abroad in our hearts by the Holy Ghost which is given unto us.” The term shed abroad denotes movement across time and space (1537). What this implies is that believers in the Old Testament of the Bible, such as king David, received the Holy Spirit just as believers in the New Testament did.
The imparting or filling of the Holy Spirit occurred on an individual basis as a result of God’s divine election. Prophets who were also known as seers were often given visions of future events that were to be communicated to God’s people. In a sense, God’s ability to transcend time is transferred to the believer through the Holy Spirit and He makes it possible for us to see what God sees.
The words of David recorded in Psalm 109:4-8 may have been a result of his seeing the crucifixion of Christ. David said, “For my love they are my adversaries…And they have rewarded me evil for good, and hatred for my love” (Psalm 109:4-5). These words do not seem to coincide with events in David’s life, but fit perfectly with Christ’s betrayal. In Psalm 109:8, David said, “Let his days be few and let another take his office.” This verse is mentioned in Acts 1:20 indicating that David’s words were prophetic.
David’s ability to see future events may be why his psalms are so timeless. Thousands of years after David lived, his psalms are still being memorized and quoted by many believers. David understood the struggles of life and was able to put them into the proper perspective, an eternal perspective with Jesus Christ at the center of it.
I believe David’s words at the end of Psalm 109 could be a picture of the day of judgement, when believers will be vindicated by Christ. “I will greatly praise the LORD with my mouth; yea I will praise him among the multitude, for he shall stand at the right hand of the poor, to save him from those that condemn his soul” (Psalm 109:30-31).
