King David sought the Lord with all of his heart (1 Kings 14:8) and God blessed him.  David sinned a few times, but when he did, he cried out to the Lord for forgiveness and the Lord was merciful and He forgave David.  King David realized that the few times he disobeyed God, he suffered consequences, and he quickly turned his heart to the Lord.

The Word of God tells us, "The eyes of the Lord run to and fro throughout the whole earth, to show Himself strong in behalf of those whose hearts are perfect toward Him..." 2 Chronicles 16:9.  The Word of God says, "You shall seek Me and find Me when you search for Me with all your heart" Jeremiah 29:13.  This is the way of God.  The Lord doesn't respond to half-heartedness. 

King David was an example of how one should seek the Lord and reap the blessings of God.  New Testament?  Jesus Himself said, "These people draw near to Me with their mouth and honor Me with their lips, but their heart is far from Me" Matthew 15:8.  He also said, "Where your treasure is, there will your heart be also" Matthew 6:21. 

Where is your heart today?  Are you seeking after money, a good time, pleasures?  How much time do you give to the Lord, versus the amount of time you spend pleasing yourself?  Boring thought?  No, never!  Once you get past your flesh standing in the way, once you overcome the flesh and spend more time with God, it becomes easier, then more enjoyable and rewarding!  We have to overcome the barriers, the "principalities, powers, rulers of the darkness of this world, spiritual wickedness in high places (Ephesians 6:12)," then, what a spiritual breakthrough! 

I know firsthand.  There was a time when it was difficult to spend 15 minutes in prayer, but I was patient, I prayed for the zeal of the Lord and I waited on the Lord for it.  Now, I am able to pray as the Holy Spirit leads and sometimes that means hours in prayer.  I have had spiritual visions, dreams, I have been taken up into glory and the Lord has allowed me to see my son, who He took to heaven in 2009.  I can't begin to describe the "heavenly places" which Paul spoke of in Ephesians 2:6. 

Where is your heart today?  Jesus said, "I know your works, that you are neither cold nor hot; I would rather you be cold or hot.  So then, because you are lukewarm, neither cold nor hot, I will spew you out of My mouth" Revelation 3:15-16. 

Does every road seem to turn into a dead end?  Is there an emptiness that hasn't been filled?  The Spirit of the Lord said, "...come...take the water of life freely" Revelation 22:17. 

Many people today want all of God's blessings, yet they have left off seeking after Him with all of their hearts.  The Word of God says, "Give, and it shall be given to you, good measure, pressed down, shaken together and running over, shall men give to you, for with the same measure that you give, it shall be measured to you again" Luke 6:38.  This is not only a spiritual law about giving, but it is also a spiritual law about giving of yourself to the Lord.  God bless you.
