1 Timothy 6:12

12Fight the good fight of the faith. Take hold of the eternal life to which you were called when you made your good confession in the presence of many witnesses.

2 Timothy 1:6-17

6For this reason I remind you to fan into flame the gift of God, which is in you through the laying on of my hands. 7For the Spirit God gave us does not make us timid, but gives us power, love and self-discipline. 8So do not be ashamed of the testimony about our Lord or of me his prisoner. Rather, join with me in suffering for the gospel, by the power of God. 9He has saved us and called us to a holy life—not because of anything we have done but because of his own purpose and grace. This grace was given us in Christ Jesus before the beginning of time, 10but it has now been revealed through the appearing of our Saviour, Christ Jesus, who has destroyed death and has brought life and immortality to light through the gospel. 11And of this gospel I was appointed a herald and an apostle and a teacher. 12That is why I am suffering as I am. Yet this is no cause for shame, because I know whom I have believed, and am convinced that he is able to guard what I have entrusted to him until that day.

13What you heard from me, keep as the pattern of sound teaching, with faith and love in Christ Jesus. 14Guard the good deposit that was entrusted to you—guard it with the help of the Holy Spirit who lives in us.

15You know that everyone in the province of Asia has deserted me, including Phygelus and Hermogenes.

16May the Lord show mercy to the household of Onesiphorus, because he often refreshed me and was not ashamed of my chains. 17On the contrary, when he was in Rome, he searched hard for me until he found me. 18May the Lord grant that he will find mercy from the Lord on that day! You know very well in how many ways he helped me in Ephesus.

Christian life is a war fare, it is a battle, and it is for Christ.

2 Timothy 4:7

7I have fought the good fight, I have finished the race, I have kept the faith.

Fight the good fight in your Christian life and win the battle. At the main time bear the witness for LORD Jesus Christ.

You got to be strong in the battle.

You cannot be ashamed of the message and messenger. Be strong and courageous.

2 Timothy 3:12

12In fact, everyone who wants to live a godly life in Christ Jesus will be persecuted,

They were persecuted by;

Unbelieving Jews

Believing Jews

Criticizers

Roman Government

Acts 20:28-31

28Keep watch over yourselves and all the flock of which the Holy Spirit has made you overseers. Be shepherds of the church of God, which he bought with his own blood. 29I know that after I leave, savage wolves will come in among you and will not spare the flock. 30Even from your own number men will arise and distort the truth in order to draw away disciples after them. 31So be on your guard! Remember that for three years I never stopped warning each of you night and day with tears.

You cannot fight apart from the Spirit of GOD. We are not even equip to live Christian life apart from the Spirit. The Spirit of GOD enables you, powers you then you can began to fulfil the commission given to you. Daily trusting Him, yielding upon Him, serving Him, facing hardship and suffering for the gospel according to power of GOD. Hang in there, when the going gets tough it requires courage and confidence. The boldness rests on confidence. Be confident because GOD had a purpose to save you and live a holy life. Yours is a holy calling. This is the purpose of GOD provided by His grace. Stand firm and be strong testimony of the gospel and LORD Jesus Christ. You have a reason to be confident because of your position in LORD Jesus Christ.

He brought the light through the gospel that we have eternal life and GOD saved us to make us His own.
