In this Psalm the writer is expressing his deep love for the Lord and how he longs to dwell in Him. Even the sparrow understands the importance to be close to You, O' GOD. Look at how the writer calls those blessed that dwells in the Lord and whose strength is in Him. As we grow in Christ and continue to learn of GOD we should become stronger day by day.
Do not become weary in well doing or think that there is a better way. The writer is saying that better is one day in GODs house than a 1,000 days elsewhere. That is so awesome. When you experience the presence of GOD you will understand, you may not be able to explain the feeling but you will know that everything will be alright.
Blessed is he that trusts in the Lord.
For the LORD God is a sun and shield; the LORD bestows favor and honor; no good thing does He withhold from those whose walk is blameless. Psalms 84:11
How lovely is your dwelling place, LORD Almighty! 2 My soul yearns, even faints, for the courts of the LORD; my heart and my flesh cry out for the living God. 3 Even the sparrow has found a home, and the swallow a nest for herself, where she may have her young— a place near your altar, LORD Almighty, my King and my God. 4 Blessed are those who dwell in your house; they are ever praising you. 5 Blessed are those whose strength is in you, whose hearts are set on pilgrimage. 6 As they pass through the Valley of Baka, they make it a place of springs; the autumn rains also cover it with pools. 7 They go from strength to strength, till each appears before God in Zion. 8 Hear my prayer, LORD God Almighty; listen to me, God of Jacob. 9 Look on our shield, O God; look with favor on your anointed one. 10 Better is one day in your courts than a thousand elsewhere; I would rather be a doorkeeper in the house of my God than dwell in the tents of the wicked. 11 For the LORD God is a sun and shield; the LORD bestows favor and honor; no good thing does he withhold from those whose walk is blameless. 12 LORD Almighty, blessed is the one who trusts in you.
