Psalm 24:3‭-‬5 KJV Who shall ascend into the hill of the LORD? Or who shall stand in his holy place? He that hath clean hands, and a pure heart; Who hath not lifted up his soul unto vanity, nor sworn deceitfully. He shall receive the blessing from the LORD, And righteousness from the God of his salvation. We must ask the Holy Spirit to search us and if there be anything in us that is not of him to expose and remove before we can present our petition to the Lord. Also our heart posture meaning our thoughts must be right and pure.
