In Philippians 4:5, what does Paul mean by "the Lord is at hand"?
That God is near to hear the prayers of his servants.
Philippians 4:5-6 NASB
5 Let your gentle spirit be known to all people. The Lord is [a]near.
6 Do not be anxious about anything, but in everything by prayer and
pleading with thanksgiving let your requests be made known to God.
The Lord is at hand or near( other translations ). God draws near to those that draw near him, in that he hears their prayer and saves his servants who are crushed in spirit. Do not be anxious about anything (Vs 6a), Paul may have been concerned about the spiritual and material welfare of fellow believers, under such circumstances he encourages them to make their petitions known to God.
James 4:8 NET
8 Draw near to God and he will draw near to you. Cleanse your hands,
you sinners, and make your hearts pure, you double-minded.[a]
Psalm 34:18 NASB
18 The Lord is near to the brokenhearted And saves those who are
[a]crushed in spirit.
Acts 17:27 NASB
27 that they would seek God, if perhaps they might feel around for Him
and find Him, though He is not far from each one of us;
