Seek First the Kingdom of God - simply means giving all you have to God, and allowing Him to sort out your issues in His own way of doing things. All you need to do is to invite Him in your adversaries and allow Him to finish the business. Let Him carry all your burdens and troubles, and you will begin to see the results of being an obedient servant of God. We need to be closer to God in daily basis. The word of God is like applying a lotion on your body, you can only realise that you didn't apply enough of your favourite lotion by seeing unusual side effects such as rash, allergy reactions, and so forth; same applies to the word of God, you can only realise that you kept too much distance away from God by experiencing issues such loneliness, self-resentment, tiredness, low self-esteem, and so forth.
If you read the word on daily basis, your brain will be fed with positivism and rewarding outcomes. Be blessed and you are blessed to be a blessing.
