Final answer:
Paul's ability to labor so abundantly was attributed to his intense faith, prayer, and divine inspiration. His teachings inspired others like Thecla to follow the Christian faith, and his community of followers provided support for his mission. Miraculous events and answered prayers are also highlighted as sources of his strength.
Step-by-step explanation:
The question 'What was with Paul to enable him to labor so abundantly?' appears to be referring to the zeal and divine inspiration which Apostle Paul possessed according to Christian texts, enabling him to spread the Christian faith and persist in his missionary work. The excerpts provided suggest that Paul's faith, his dedication to prayer, and especially divine assistance, as seen where Paul prays for Thecla and is answered by God, are what empowered him to be such an effective and tireless worker for the early Christian movement.
Moreover, the interaction with Thecla illustrates the powerful influence of Paul's teachings and how they inspired others to follow the Christian faith despite the challenges and temptations they may face. Thecla's determination to cut her hair and follow Paul signifies a break from traditional roles and a commitment to a life dedicated to faith, which is catalyzed by Paul's teachings and guidance.
It is important to recognize how Paul's missionary journeys, his fasting and prayers, and the support of his followers, like Onesiphorus and his family, were pivotal in his labor. These acts of faith were believed to be supported by divine provision, signified by miraculous events such as being provided with food through faith, and direct interactions such as Thecla being saved from harm and choosing to follow Paul after witnessing God answering Paul's prayers.
