So as we left Patrick, he ran away from his master and traveled a great distance to find a boat. He believes God called him to follow this path. The boat owners turn him down and tell him no way can he sail on their ship. Patrick turns and walks away praying.
Hearing this I left them to go to the hut where I was staying, and on the way I began to pray, and before the prayer was finished I heard one of them shouting loudly after me: “Come quickly because the men are calling you.” And immediately I went back to them and they started to say to me: “Come, because we are admitting you out of good faith; make friendship with us in any way you wish.” (And so, on that day, I refused to suck the breasts of these men from fear of God, but nevertheless I had hopes that they would come to faith in Jesus Christ, because they were barbarians.) And for this I continued with them, and forthwith we put to sea.
The fact God calls us does not mean there will not be obstacles but we should preserve as Patrick did. He prayed asking God to show him the way. God answered Patrick immediately, sometimes we have to wait and pray longer than Patrick did. But if God calls a person, and the person holds to faith and trusts God, the Lord will open the path.
Look at Moses. God called the Israelite out of Egypt. Before them was Red Sea and behind them the armies of Egypt.
Exodus 14:13 And Moses said unto the people, Fear ye not, stand still, and see the salvation of the Lord, which he will shew to you to day: for the Egyptians whom ye have seen to day, ye shall see them again no more for ever.
14 The Lord shall fight for you, and ye shall hold your peace.
15 And the Lord said unto Moses, Wherefore criest thou unto me? speak unto the children of Israel, that they go forward:
16 But lift thou up thy rod, and stretch out thine hand over the sea, and divide it: and the children of Israel shall go on dry ground through the midst of the sea.
17 And I, behold, I will harden the hearts of the Egyptians, and they shall follow them: and I will get me honour upon Pharaoh, and upon all his host, upon his chariots, and upon his horsemen.
18 And the Egyptians shall know that I am the Lord, when I have gotten me honour upon Pharaoh, upon his chariots, and upon his horsemen.
19 And the angel of God, which went before the camp of Israel, removed and went behind them; and the pillar of the cloud went from before their face, and stood behind them:
20 And it came between the camp of the Egyptians and the camp of Israel; and it was a cloud and darkness to them, but it gave light by night to these: so that the one came not near the other all the night.
21 And Moses stretched out his hand over the sea; and the Lord caused the sea to go back by a strong east wind all that night, and made the sea dry land, and the waters were divided.
22 And the children of Israel went into the midst of the sea upon the dry ground: and the waters were a wall unto them on their right hand, and on their left.
23 And the Egyptians pursued, and went in after them to the midst of the sea, even all Pharaoh’s horses, his chariots, and his horsemen.
24 And it came to pass, that in the morning watch the Lord looked unto the host of the Egyptians through the pillar of fire and of the cloud, and troubled the host of the Egyptians,
25 And took off their chariot wheels, that they drave them heavily: so that the Egyptians said, Let us flee from the face of Israel; for the Lordfighteth for them against the Egyptians.
26 And the Lord said unto Moses, Stretch out thine hand over the sea, that the waters may come again upon the Egyptians, upon their chariots, and upon their horsemen.
