“For the word of the LORD is right and true; he is faithful in all he does. The LORD loves righteousness and justice; the earth is full of his unfailing love.”
When I read these two verses out of the Psalms the first thing that comes to mind is when James states, “If any of you lacks wisdom, let him ask God, who gives generously to all without reproach, and it will be given him. But let him ask in faith, with no doubting, for the one who doubts is like a wave of the sea that is driven and tossed by the wind. For that person must not suppose that he will receive anything from the Lord; he is a double-minded man, unstable in all his ways.” To me James is referring to what it states in Psalm 33:4 by stating how when we doubt when asking God for something as simple as wisdom we are doubting the nature of God. The Psalmist states that the word of the Lord is right and true, and that He is faithful in all He does.
What this means for us is that the universal promises found in the Bible we as believers can be sure that God will fulfill. Promises such as wisdom if we are to ask for it; but we need to have faith, to trust and believe that God is faithful. If we cannot rest in that truth, we find ourselves being tossed around like a wave in the ocean. We need to hold on to the foundational principle of our faith that the Lord is right and true, as well as that He does fulfill His promises; it may not be when or in the way we want them to be fulfilled, but He will fulfill them.
