Acts 2 describes the events of the day of Pentecost. Before the day ended, God had saved 3,000 people. But if God saved 5,000 people tomorrow, Pentecost would still be a far more important day.

Why? Why should we consider Pentecost to be one of the most important days in the history of the world?

Most Christians would answer: Pentecost is important because on that day the Holy Spirit came. But we know the Holy Spirit was active prior to this day. So what changed? And why is this change so important?

Let’s look at this by, first, considering how the relationship of the Holy Spirit to believers is the same before and after Pentecost. Next week we’ll consider how that relationship changes on this momentous day.

How is the relationship of the Spirit to Believers Similar Before and After Pentecost?

Five ways:

1) The Spirit gives life to those who believe

This statement is true of all believers of all time

Consider Ephesians 2:1-5, one of the most important biblical passages describing salvation:

You were dead in the trespasses and sins in which you once walked, following the course of this world, following the prince of the power of the air, the spirit that is now at work in the sons of disobedience– among whom we all once lived in the passions of our flesh, carrying out the desires of the body and the mind, and were by nature children of wrath, like the rest of mankind.  (Ephesians 2:1-3)

Paul makes clear that he is not speaking only about the readers of this letter, for he says we are by nature objects of God’s wrath. That is, God, as the moral authority of the universe, must mete out punishment in response to our sinful nature, not only our sinful deeds. And since this holds “for the rest of mankind,” this is true of all men everywhere at all times since the Fall. No one is able do anything on his own to change his being under God’s wrath.

But God, being rich in mercy, because of the great love with which he loved us, even when we were dead in our trespasses, made us alive together with Christ. (Ephesians 2:4-5)

“But God!” Only He could change our condition. He makes us alive; He enables us to believe; He cuts through the blinding fog so that we might see Him.

There has never been anyone saved by any means other than by God’s grace through faith. This is true before Pentecost and after Pentecost: The Spirit gives life to those who believe.

2) The Spirit gives love for the character of God, and thus for His Law

The Law is a reflection of the character of God, helping us to know Who He is. So the one who loves God must love His Law.

This is one of the New Covenant promises in Jeremiah 31: That His people will have His Law written on their hearts. There will be an inner change, not only external obedience to rules.

But while Jeremiah 31 is not fulfilled until after Pentecost, there are those in the Old Testament who have a similar inner change – who have the Law on their hearts, who love God’s Law. Consider the following verses:

• Isaiah 51:7 Listen to me, you who know righteousness, the people in whose heart is my law.
• Psalm 119:97  Oh how I love your law! It is my meditation all the day.
• Psalm 119:18-19   Open my eyes, that I may behold wondrous things out of your law. I am a sojourner on the earth; hide not your commandments from me!

Note that in Psalm 119:18-19, the psalmist acknowledges that this love for God’s Law is God-given.

So before and after Pentecost, God engenders love for His character, for His Law, in the hearts of people.

3) The Spirit is constantly with those who believe

This is clearly true after Pentecost, as it is another of the New Covenant promises contained in Ezekiel 36:27: “I will put my Spirit within you.”

But hear what David says:

Psalm 139:7-10  Where shall I go from your Spirit? Or where shall I flee from your presence? If I ascend to heaven, you are there! If I make my bed in Sheol, you are there! If I take the wings of the morning and dwell in the uttermost parts of the sea, even there your hand shall lead me, and your right hand shall hold me.

David is not only saying, “God is everywhere.” He is also saying, “No matter where I go – even if I am being rebellious, trying to flee from You – You are with me, leading me, holding me.”

So the Spirit’s presence with believers was real before and after Pentecost.

4) The Spirit enables obedience in those who believe

Again this is obviously true after Pentecost; it is the Spirit that bears the fruit of love, joy, and peace in believers (Galatians 5:22-23). And Ezekiel had prophesied that God would “cause you to walk in my statutes” (Ezekiel 36:27).

But before Pentecost, David says, ‘He leads me in paths of righteousness for his name’s sake” (Psalm 23:8)

Or as the author of Psalm 119 writes:

Make me walk in the path of Your commandments, For I delight in it. Incline my heart to Your testimonies And not to dishonest gain. Turn away my eyes from looking at vanity, And revive me in Your ways. (Psalm 119:35-37 NAS)

The Spirit enabled obedience in believers before and after Pentecost.

5) The Spirit enables perseverance in those who believe

Once again, this is clear after Pentecost; 1 Thessalonians 5:23-24 and many other passages teach this truth.

But consider the perseverance in faith of Old Testament characters. We have already seen from Ephesians 2 that faith is a gift of God. In Hebrews 11, the author lists many Old Testament characters who display extraordinary faith. After summarizing the difficulties they endured, he concludes:

Destitute, persecuted and mistreated– the world was not worthy of them. They wandered in deserts and mountains, and in caves and holes in the ground. These were all commended for their faith (Hebrews 11:37b-39a)

This is extraordinary perseverance. And it is the result of Spirit-given faith.

The Spirit has always been at work. No one would ever believe, ever obey, ever persevere apart from the Spirit. As Jesus says in John 15:5, “Apart from me you can do nothing.” He was speaking to his disciples, using present tense, before Pentecost. And His statement is therefore true of all men, of all times.
