‘looking to Jesus, the author and finisher of our faith…’ Hebrews 12:2

Here are some tips that you can choose to apply to your writing. Decide for yourself.

Write so that your product will provide consumers with joy. 
Galatians 5:22-23 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faith, 23 gentleness, self-control. Against such things there is no law.

Write what is in your heart. Don’t write what you think people will like or to please other people. Follow your heart when you write and be true to who you are and what you want to say. 
Luke 6:45 A good man produces good out of the good storeroom of his heart. An evil man produces evil out of the evil storeroom, for his mouth speaks from the overflow of the heart.

Believe in your vision for what you want to write. 
The Apostle John was directed in writing the book of Revelation to “Therefore write what you have seen, what is, and what will take place after this.” Revelation 1:19

Learn the art of writing. Practice the discipline of writing. 
Proverbs 23:12 Apply yourself to discipline and listen to words of knowledge.

To communicate a message understand what you are saying. Be sincere, have a clear conscience, and seek to find the purist form in your words. Avoid abstract, vague, confusing language. The Apostle Paul uses this advice when sharing with Timothy how he should stay true to the message they are supposed to be teaching. 
1 Timothy 1:5-7 Now the goal of our instruction is love that comes from a pure heart, a good conscience, and a sincere faith. 6 Some have deviated from these and turned aside to fruitless discussion. 7 They want to be teachers of the law, although they don’t understand what they are saying or what they are insisting on.

Think of your writing as a sacrificial gift to others, and expect to be paid what it is worth. 
Acts 20:35 includes part of the Apostle Paul’s direction to the church elders in Ephesus. In it he states “In every way I’ve shown you that by laboring like this, it is necessary to help the weak and to keep in mind the words of the Lord Jesus, for He said, ‘It is more blessed to give than to receive.’ ”. 
Likewise when Paul wrote to the churches in Galatia he advised them similarly “For each person will have to carry his own load. 6 The one who is taught the message must share all his good things with the teacher. 7 Don’t be deceived: God is not mocked. For whatever a man sows he will also reap,” Galatians 6:5-7a.

Apply careful investigation to what you write.
The Gospel attributed to Luke begins with this explanation: “Many have undertaken to compile a narrative about the events that have been fulfilled among us, 2 just as the original eyewitnesses and servants of the word handed them down to us. 3 It also seemed good to me, since I have carefully investigated everything from the very first, to write to you in an orderly sequence, most honorable Theophilus, 4 so that you may know the certainty of the things about which you have been instructed.” Luke 1:1-4

Have a clear and specific purpose for everything you write.
Joshua 18:4 Provide for yourselves three men from each tribe that I may send them, and that they may arise and walk through the land and write a description of it according to their inheritance; then they shall return to me.

Write when you find yourself most challenged. Write when it seems like it’s the last thing you should do. When in doubt, write. No matter what excuse you have not to write, write anyway.
Here in John 8:6 is an example of what Jesus did: “They were saying this, testing Him, so that they might have grounds for accusing Him. But Jesus stooped down and with His finger wrote on the ground.”

Write for a higher standard. 1 Corinthians 4:3-5 “It is of little importance to me that I should be evaluated by you or by any human court. In fact, I don’t even evaluate myself. 4 For I am not conscious of anything against myself, but I am not justified by this. The One who evaluates me is the Lord.”
