The fourth Beatitude reads: “Blessed are they which do hunger and thirst after righteousness: for they shall be filled.” (Matthew 5:6)
In the fourth Beatitude, Jesus gave a promise to all who desire to order their lives after the righteousness of God. This promise was that they shall be satisfied with fullness of joy in their hearts for this is the results of being filled with the righteousness of God.
One is filled as he partakes of the blessing being offered to him of God. But before this filling there must first be a desire which is created by a hungering and thirsting for the good thing that God has promised. The natural desire for food is created by hunger pangs. Likewise, the spiritual desire for righteousness is created by a spiritual hunger and thirst. This spiritual hunger and thirst is caused by conviction which God initiates through His love for us as we can see in the famous scripture verse in John 3:16.
David expressed this thirsting after God in Psalms 43:1; “As the hart (deer) panteth after the water brooks, so panteth my soul after thee, O God.” In Jeremiah 6:37 God promised Israel restoration if they would search for Him with all their heart. The intense desire for righteousness must be with the whole heart and when we seek God with all that is within us we will certainly find Him. In Romans 10:13 we are told that “…whosoever shall call upon the name of the Lord shall be saved.” And in John 6:37 Jesus promised; “…and him that cometh to me I will in no wise cast out.” In John 4:14 Jesus said: “But whosoever drinketh of the water that I shall give him shall never thirst; but the water that I shall give him shall be in him a well of water springing up into everlasting life.”
Very often we meet people who tell us that they have gone too far and cannot be saved or that they are too bad to be saved. Such thoughts as these are false in light of the above referenced scriptures. Their problem is that they do not have a huger nor thirst to be saved. All who will allow the conviction of the Holy Spirit to touch their heart can find peace in their hearts. God has assured this in His Holy Word.
It is true that some do go so far as not to feel conviction any longer and because of this they will never be saved. But people in this condition have no desire to pray for forgiveness for they do not recognize their need to be saved because this recognition can only come about through conviction.
Conviction is a divine act of God in the heart of the lost person. When God turns a person over to eternal damnation it is because they have so hardened their heart that they can no longer feel conviction for without godly conviction, one does not know that he needs to repent. Therefore, all who desire and have a hunger or thirst for salvation can be saved, but only as they respond through repentance. When they repent, they then begin to enjoy this filling of righteousness from God as He has promised. And this filling of righteousness is truly a great blessing as proclaimed in the fourth Beatitude; “Blessed are they which do hunger and thirst after righteousness: for they shall be filled.”
