Philippians 4:8 (HCSB)
8 Finally brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable—if there is any moral excellence and if there is any praise—dwell on these things.

Meditation means different things to different people, some equates it to eastern religion, yoga and relaxation but the bible gives a different definition to meditation.
Meditation is close or continued turning of a subject in the mind in serious contemplation.
The scriptures encourage us to meditate on God’s word first in Joshua 1:9, this is to fully focus on God’s word with an expectation of spiritual revelation brought from deep thought.
According to Psalm 1:2, our delight in the law of the Lord should encourage us to meditate on it day and night.
Meditating on the word of God describes concentrated thinking on a particular piece of scripture to gain an answer, understanding or revelation. Believers should face every situation in life with a desire to please God.
Other kinds of meditations may spore us to change our lifestyles, and habits but meditating on the Word of God changes us completely both physically and spiritually while helping us grow into maturity in the word.
Meditating on the right things according to Philippians 4:9 helps us practise kingdom-mindedness, putting the things we learn in what we do.
Biblical meditation is looking back at the things the Lord has done in our lives and pondering on the promises in the scriptures that we’re meditating on.
When David got to the end of himself in Psalm 143:4-5, de didn’t give up, he instead remembered the olds by meditating on God’s goodness to him, from which he drew strength and courage to carry on.
The weariness of the soul must push us to thirsts for God as the only source of energy capable of refreshing and re-energising us.
It is the deep meditation on the word of God that helps us achieve what Psalm 119:11 talks about-storing God’s word in our hearts to help us avoid sinning against God. The CSB translation uses “treasure” instead of stored, that is precisely what the word of God becomes within us through meditation. So, by treasuring the word of God in our hearts, we train ourselves to not just love God’s ways, instructions and principles, but according to James 1:22, we become doers and not hearers of the word alone.
Meditation is a vital part of the Christian walk and as one anonymous writer said, “The Bible is not meant merely to inform but to transform.” Contemplating on the word of God in meditation is what helps us understand God’s status and appreciate His wonders as stated in Psalm 119:27.
Meditating on the word of God leads us to ponder on scripture that helps us ask God pertinent questions that we then practise to establish our faith, leading us to praise God.
There are no gurus or masters needed for biblical meditation. The bible is full of pictures and stories to draw inspiration from, there is no shortage of topics or activities to think on as encouraged in our text, through meditation, we fill our hearts and then our mouths with holy and acceptable things which in turn begins to affect our character and attitude that the world around us responds to.
We mustn’t meditate on the wrong things, not on evil or negative things either but Psalm 19:14 put it clearly, both the words of our mouth and the meditations of our hearts must be acceptable to the Lord.
Shalom
