1. More precious thing than our life : Testifying the gospel of the grace of God (Acts 20:22-24)
    Acts 23:12-14, Acts 20:31-32, 36-38, Acts 21:10-14

The Jews pursued Paul to kill him. (Acts 23:12-14)

Acts 23:12 And when it was day, certain of the Jews banded together, and bound themselves under a curse, saying that they would neither eat nor drink till they had killed Paul.
13 And they were more than forty which had made this conspiracy.
14 And they came to the chief priests and elders, and said, We have bound ourselves under a great curse, that we will eat nothing until we have slain Paul.

But Paul did not regard his life as precious to finish preaching the gospel of God’s grace, that is, that Jesus was the Christ. (Acts 20:22-24)

Acts 20:22 And now, behold, I go bound in the spirit unto Jerusalem, not knowing the things that shall befall me there:
23 Save that the Holy Ghost witnesseth in every city, saying that bonds and afflictions abide me.
24 But none of these things move me, neither count I my life dear unto myself, so that I might finish my course with joy, and the ministry, which I have received of the Lord Jesus, to testify the gospel of the grace of God.

Paul preached this gospel to his disciples for three years. (Acts 20:31-32, 36-38)

Acts 20:31 Therefore watch, and remember, that by the space of three years I ceased not to warn every one night and day with tears.
32 And now, brethren, I commend you to God, and to the word of his grace, which is able to build you up, and to give you an inheritance among all them which are sanctified.
36 And when he had thus spoken, he kneeled down, and prayed with them all.
37 And they all wept sore, and fell on Paul’s neck, and kissed him,
38 Sorrowing most of all for the words which he spake, that they should see his face no more. And they accompanied him unto the ship.

A prophet prophesied that Paul would be arrested if he went to Jerusalem, but Paul was prepared to die in Jerusalem to preach the gospel that Jesus is the Christ. (Act 21:10-14)

Act 21:10 And as we tarried there many days, there came down from Judaea a certain prophet, named Agabus.
11 And when he was come unto us, he took Paul’s girdle, and bound his own hands and feet, and said, Thus saith the Holy Ghost, So shall the Jews at Jerusalem bind the man that owneth this girdle, and shall deliver him into the hands of the Gentiles.
12 And when we heard these things, both we, and they of that place, besought him not to go up to Jerusalem.
13 Then Paul answered, What mean ye to weep and to break mine heart? for I am ready not to be bound only, but also to die at Jerusalem for the name of the Lord Jesus.
14 And when he would not be persuaded, we ceased, saying, The will of the Lord be done.
