The most important thing we can do with the Word is to give it our whole hearted attention. “My son, give attention to my words; incline your ear to my sayings. Do not let them depart from your eyes; keep them in the midst of your heart.” (Prov. 4:20-21). If we keep our eyes on the Word it will crowd doubt out of our minds.
We should keep God’s Words, and treasure them within us. “My son, keep my words, and treasure my commands within you.” (Prov. 7:1).

Treasuring God’s Word means meditating on it with pleasure (Ps. 1:1- 3), knowing that God’s Word in your heart will produce spiritual riches.
The Word of God must be mixed with faith (Hebrews 4:2) or it will not really do us very much good. “Faith comes by hearing the Word of God” (Romans 10:17), not by “having heard it”.

Therefore to build our faith we should speak the Word with our mouth much (Joshua 1:8), so we ourselves hear it and it gets into us. Hearing preaching of the Word in church or via media can build our faith very much, especially when the preacher is himself full of faith and the Holy Spirit.
However, if we can read, we ought to read and study the Scriptures also for ourselves. “Study or be diligent to present yourself approved to God, a worker who does not need to be ashamed, rightly dividing the word of truth.” (2 Tim. 2:15).
Paul said, “Till I come, give attention to reading, to exhortation, to doctrine.”(1 Tim. 4:13)

It helps greatly to memorize God’s Word, both for our own personal meditation and for the future when we will communicate it to others. We should let it consume us (1 John 2:14) like a fire. (Jer. 23:29).
Most importantly, we should obey it. True faith leads to obedience (Romans 1:5). “Blessed are those who hear the word of God and keep it!” said Jesus (Luke 11:28). “But be doers of the Word, and not hearers only, deceiving yourselves.” (James 1:22).We deceive ourselves if we think that hearing the Word is enough. We must put it into practice. Otherwise our faith is dead.
Once we have begun to obey the Word as disciples of Christ, we should preach it to others (2 Tim. 4:2) so that they can be saved, and teach it to others in a practical way. Jesus said, “Teach them to obey all that I have commanded you.” (Matthew 28:20).
This book of the Law shall not depart from your mouth, but you shall meditate in it day and night, that you may observe to do according to all that is written in it. For then you will make your way prosperous, and then you will have good success. (Joshua 1:8).
