“The Lord is the strength of my life.” Psalm 27:1

King David, the author of this quote, centered his life around God. He was anchored to God and looked to God for His every need. The Lord was His keeper.
You have to understand the strength of God is made perfect in your weakness. This will only come into your reality when you experience the power and glory of God and see your insignificance compared to almighty God. You will then fully grasp the futility of trying to rely on self when you can have the backing and support of God.
The spiritual man wakes up in the morning and seeks God out for strength and wisdom because he knows God is infallible and wants to give His unlimited attributes to him. He commits his works to God each day. This is how you walk with God and allow Him to live through you to meet the challenges of life.
If you try to depend on self to meet your needs, you will fail. The spiritual man realizes that God will supply his every need and give him more than he asks or thinks.
The spiritual man inquires of the Lord before making decisions because he knows God wants to protect and keep him away from trouble.
You can have the courage and strength to face any challenge in life when you walk with God. He will never leave you or disappoint you!
