The phrase “my whole heart” is found eight times in the Bible and each of them is in the book of Psalms. Of the eight occurrences in the book of Psalms, five of them are in Psalm 119. All three times the phrase appears outside Psalm 119, the psalmist is saying, “I will praise You, O Lord, with my whole heart” (9:1; 111:1; 138:1), while the five occurrences in Psalm 119 explain how that is done. Think about these. Can you say this?
“I will praise You with my whole heart,” for “with my whole heart I have sought You” (119:10). Do you seek the Lord with your whole heart? “I will praise You with my whole heart” when I “observe [Your law]” and “keep Your precepts with my whole heart” (119:34, 69). Do you obey the Lord with your whole heart? “I will praise You with my whole heart,” when “I cry out [to You] with my whole heart” and “entreat Your favor with my whole heart” (119:145, 58). Do you cry out to the Lord and entreat His favor with your whole heart?
Do you praise the Lord with your whole heart? We can’t hold anything back!
