Those who strive to constantly obey God's will are like flourishing, fruitful trees with deep roots. The psalmists praise God for His righteousness; there are hymns extolling Him as the Creator, Provider, and Redeemer of humanity. God is Almighty and always acts at the right time; He is sovereign over all circumstances. When we feel powerless, we can seek God's help; we can always pray for His deliverance and protection. The Psalms contain profound prayers; when we confess our sins and turn away from them, God forgives us. The psalmist emphasises the timeless theme of blessedness. This verse tells us what to avoid: associating with sinners and those who mock God. The Lord is righteous, and when we trust in Him, He grants peace to our hearts. Chaff is light and easily blown away by a gentle breeze, whereas the winnowed grain falls back to the ground; the chaff represents the life of the unbeliever, aimlessly tossed about, while the grain represents the life of the believer, who can be used by God. The wicked may prosper in worldly terms, but God assures us that a day of judgement will come for them. God does not judge people based on race, gender, or nationality.

A prophet is said to be a person who must bring the truths of God to the ears of the people, inspired by the Spirit of God. The house of God, that is, the church, is built on the foundation of apostles and prophets. The teachings of the church and the foundation of God's family are based on the apostles of the New Testament and the prophets of the Old Testament. In other words, the church is built on the basis of the Old Testament and the New Testament (that is, the Bible). In simpler words, the foundation and solid foundation of the church is the Word of God. The Holy Spirit has inspired the words of God to the prophets of the Old Testament and the apostles of the New Testament. They have given us the word of God. Paul pointed out another important truth, saying that Jesus Christ is the cornerstone of the church. Without Jesus Christ, the church will fall apart.
