This whole Psalm 145 is filled with great reasons to praise God. This particular reason in verse 18 is a great one for we know that He is always near us and hears us when we pray to Him with a sincere heart. Let us be thankful that we can call on God anytime, anywhere, and for all reasons of concern to us and as one man said, we never get a busy signal. God is never too busy, or never around, or never just ignores us. Let us come boldly to the throne of grace to find mercy and help in the time of need. (Hebrews 4:16) And be thankful for the many reasons we have to praise Him.
Psalm 145:18 The LORD is near to all who call on Him, to all who call on Him in truth.
