From there Paul went north into Galatia. Many Jews lived in this province. Therefore it is very probable that Paul first addressed his preaching to them and to the proselytes among them.
But the poor reception he met among the Jews opened the way to the Gentiles. The Gentiles received him with great goodwill, Gal 4:13-14: "you received me as an apostle of God, as Jesus Christ."
The infirmities in the flesh, the trial in the flesh, which the Galatian Christians did not despise, were probably his recent sufferings for the cause of Christ. He speaks of them in detail in 2 Cor 11:23-26.
Or else they were an illness of the flesh, from which he asked God three times to deliver him, but received no relief. This was so that the power of God might be made more clearly perfect in his weakness.
In the present case, his weakness was not an obstacle to the spread of the Gospel. Rather, it drew the hearts of the converts to him still more.
Seeing his zeal in the work of the Gospel, despite illness and suffering, they became all the more attached to Christ's teacher. As the apostle says, they were ready to give their own eyes for him.
Paul struggled greatly with bodily ailments, as can be seen from certain hints in his epistles. There he speaks of how the feeling of human weakness weighed upon him.
This should not seem strange. Even when he was a Pharisee, striving to attain legal holiness, he did not spare his body. His new calling allowed him still less to spare himself.
At one and the same time he had to earn his food by the labors of his hands and strain all his strength according to the duty of apostolic ministry. He had to endure so many dangers, insults, and beatings.
Even a strong body could soon have fallen beneath such a weight. Yet with the feeling of human weakness, the consciousness of a higher power became stronger in him. This power rose above everything human strength can do.
He knew how to distinguish it from everything he recognized in himself as merely human. It was that victorious power of God which appeared through his preaching of the Gospel.
Feeling his human weakness, he nevertheless rose still more above himself through inner revelations and communications with the higher world, of which he was deemed worthy.
He had one especially grievous illness, which even checked the impulses of his exalted spirit. He regarded it as an instruction in humility sent by God. It was a balancing means against the moments of inner illumination allotted to him.
He said that three times he asked the Lord to free him from this grievous illness. But the voice of God answered that he should not ask to be delivered from the feeling of human weakness.
It should be enough for him to know the grace given to him. For the power of God shows itself as such precisely where human weakness also makes itself felt.
This was revealed especially during his activity in Galatia. His body was weighed down by illness. Yet the divine power of his words and actions stood in complete contrast to the weak organ that served as its instrument.
For this reason it made an even stronger impression on hearts already disposed toward it. The fiery zeal of love, sacrificing everything, compelled him to endure all things joyfully in his very sufferings for the salvation of others.
This had to draw hearts to him with still greater power. Therefore he could speak of the Galatians' disposition toward him as he does, 4:14-15.
The Galatian churches consisted chiefly of natural Gentiles. Some were proselytes, for whom Judaism was a transition to Christianity. Others had turned to Christianity directly from paganism.
To this fundamental composition of the Church were added certain Jews, who differed from the greater mass of their unbelieving countrymen by their receptivity to the Gospel.
Through proselytes and Christians from among the Jews, relations with the Jews did not cease in this Church. From this source we must derive the movements that we later see in the Galatian churches.
When Paul left Galatia, he wanted to take a southwesterly direction into proconsular Asia, where Ephesus lay on the Aegean shore. But by an inner voice, or in a vision, the command of the Spirit of God was announced to him. It restrained him from this direction.
