Verse 18 sets up the scenario: some are arrogant, thinking Paul won't come. Verse 19 directly responds by threatening a visit to test their power.

Verse 6 warns against being puffed up over leaders—the same prideful attitude that Paul confronts in verse 19 when he threatens to come and expose empty talk.

In 1 Cor 11:34, Paul again says he will set things in order when he comes — reinforcing his planned visit to address issues.

In 1 Cor 16:7, Paul similarly says 'if the Lord permits' about his visit — echoing the same conditional planning.

In 1 Cor 16:3, Paul refers to his arrival in Corinth for the collection — another mention of his planned visit.

2 Corinthians 1:17 defends Paul's change of plans — referencing the same intended visit as 1 Cor 4:19, questioning if he was fickle.

James 4:15 provides the classic NT teaching: human plans must be qualified by 'if the Lord wills,' which is exactly what Paul models here.

In 2 Corinthians 13:1-4, Paul carries out this threatened visit, confronting the arrogant with power rather than words—fulfilling the promise here.

2 Corinthians 2:1 states Paul decided not to come in sorrow — a direct follow-up to his announced intention in 1 Cor 4:19 to visit.

In 2 Corinthians 1:23, Paul explains he postponed his visit to spare them — revealing why the promise in 1 Cor 4:19 was not immediately fulfilled.

In Acts 18:21, Paul similarly conditions his return on God's will, reinforcing his consistent practice of submitting travel plans to divine sovereignty.

In 2 Corinthians 1:15, Paul recalls his intention to visit Corinth for a 'second benefit' — directly echoing the plan promised in 1 Cor 4:19.

Romans 15:32 echoes this same conditional language—Paul hopes to come by God's will—showing a recurring pattern in his ministry.

Acts 19:21 records Paul's plan to pass through Macedonia and Achaia — the same journey he announces in 1 Cor 4:19 to visit Corinth.

In 2 Cor 10:2, Paul again speaks of his coming presence and warns of bold action — a later echo of his intent to test 'power'.

In 2 Cor 10:11, Paul insists his actions will match his words when present — reinforcing the 'power not word' test of 4:19.

Romans 1:10 shows Paul's same practice of submitting travel plans to God's will, making the conditional phrase a hallmark of his missionary strategy.

In 2 Cor 13:2, Paul warns he will not spare them when he comes — a direct fulfillment of his intention to test and act in 4:19.

In 2 Cor 12:14, Paul mentions being ready to come a third time — continuing the theme of his planned visits to Corinth.

Hebrews 6:3 uses the broader principle 'if God permits,' affirming that all Christian plans depend on God's allowance, just as Paul's visit does.
