 From that time forward Timothy was Paul's constant companion. He was left behind at Beroea with Silas when Paul escaped to Athens, and later joined him there ( Acts 17:14-15, Acts 18:5). He was sent as Paul's emissary to Macedonia ( Acts 19:22). He was there when the collection from the Churches was being taken to Jerusalem ( Acts 20:4). He was with Paul in Corinth when Paul wrote his letter to Rome ( Romans 16:21). He was Paul's emissary to Corinth when there was trouble in that unruly Church ( 1 Corinthians 4:17; 1 Corinthians 16:10). He was with Paul when he wrote 2 Corinthians ( 2 Corinthians 1:1; 2 Corinthians 1:19). It was Timothy whom Paul sent to see how things were going in Thessalonica and he was with Paul when he wrote his letter to that Church ( 1 Thessalonians 1:1; 1 Thessalonians 3:2; 1 Thessalonians 3:6). He was with Paul in prison when he wrote to Philippi, and Paul was planning to send him to Philippi as his representative ( Php_1:1 ; Php_2:19 ). He was with Paul when he wrote to the Church at Colossae and to Philemon ( Colossians 1:1; Philemon 1:1). Constantly Timothy was by Paul's side, and when Paul had a difficult job to do Timothy was the man sent to do it.
