Matthew Henry Commentary Psalms 138:6-8

"For though Jehovah is high, yet hath he respect unto the lowly; But the haughty he knoweth from afar. Though I walk in the midst of trouble, thou wilt revive me; Thou wilt stretch forth thy hand against the wrath of mine enemies, And thy right hand will save me. Jehovah will perfect that which concerneth me: Thy lovingkindness, O Jehovah, [endureth] for ever; Forsake not the works of thine own hands." — Psalms 138:6-8 (ASV)

Though the Lord is high, yet he has respect for every lowly, humbled sinner; but the proud and unbelieving will be banished far from his blissful presence. Divine consolations have enough in them to revive us, even when we walk in the midst of troubles.

And God will save his own people so that they may be revived by the Holy Spirit, the Giver of life and holiness. If we give God the glory of his mercy, we may take the comfort to ourselves.

This confidence will not lessen prayer, but rather will enliven it. Whatever good there is in us, it is God who works in us both to will and to do. The Lord will perfect the salvation of every true believer, and he will never forsake those whom he has created anew in Christ Jesus to good works.
