Usually when we or others use I, me, my often indicates self-centeredness.But there are times when I ,me, my are in a good sense as the above eight verses show. The words I, me, my appeared 13 times in the eight verses. But let us see what is different.
If we open our Bible on the above verses the center or focus is not the I, me, my but the psalmist is focused on God, His law, His word, His salvation, His statutes,His mercy ,His judgments, His testimonies,His precepts,His lovingkindness ,His truth.
In short, let us turn our selfie to focus on the Deity.
