Principle of divine multiplication

From the beginning of creation, multiplication has been central to the agenda and purpose of God for humanity. The Lord in His infinite wisdom chose His words when He proclaimed His first blessing upon mankind.

God deliberately started His proclamation with “Be fruitful”.

What does it mean to be fruitful?

Fruitfulness is a form of multiplication, because when a single seed of corn or a tiny portion of some other crop is planted, at the time of harvest it usually brings forth multiple folds of what was planted. After God proclaimed “Be fruitful”, He thereafter commanded the multiplied fruits to be multiplied again, culminating in what is known as progressive multiplication.

God didn’t stop there; He went ahead to make another related decree, saying “Replenish the earth”.

To replenish the earth is to nourish and prepare the ground to produce and accommodate future harvests successfully.

The principle of multiplication

Thanksgiving. If you want to be blessed, learn to offer quality thanksgiving to God for His love and mercy, goodness and favor. Sing praises to God for who He is: the King of kings, the Lord of lords, the Ancient of days, and the Lord of Hosts.

You cannot praise and worship God enough; therefore, keep spending quality time praising Him.

Giving - Giving involves paying tithes and offerings, sponsoring the propagation of the gospel of Jesus, and getting involved in the work of ministry. Giving is a time tested aspect of the principle of multiplication, confirmed by the Lord Himself in Luke 6:38.
A diligent worker. God promised in several passages of the Bible to bless the work of our hands
Christians must have a livelihood and be committed to working hard before they can hope for multiplication.
Holy living and prayer.

You do not be satisfied with the grace that you already have. Be thankful for it but don’t go to sleep over past successes. Believe God and serve Him in holiness.

God never promises the church the kinds of blessings that he promised Israel. The New Testament it talks almost exclusively about spiritual blessings. Like this:

(Ephesians 1:3-14 NIV) Praise be to the God and Father of our Lord Jesus Christ, who has blessed us in the heavenly realms with every spiritual blessing in Christ. {4} For he chose us in him before the creation of the world to be holy and blameless in his sight. In love {5} he predestined us to be adopted as his sons through Jesus Christ, in accordance with his pleasure and will-- {6} to the praise of his glorious grace, which he has freely given us in the One he loves. {7} In him we have redemption through his blood, the forgiveness of sins, in accordance with the riches of God's grace {8} that he lavished on us with all wisdom and understanding. {9} And he made known to us the mystery of his will according to his good pleasure, which he purposed in Christ, {10} to be put into effect when the times will have reached their fulfillment--to bring all things in heaven and on earth together under one head, even Christ. {11} In him we were also chosen, having been predestined according to the plan of him who works out everything in conformity with the purpose of his will, {12} in order that we, who were the first to hope in Christ, might be for the praise of his glory. {13} And you also were included in Christ when you heard the word of truth, the gospel of your salvation. Having believed, you were marked in him with a seal, the promised Holy Spirit, {14} who is a deposit guaranteeing our inheritance until the redemption of those who are God's possession--to the praise of his glory.

I don't think much of posts where talk about how to get blessings from God. I think they show a lack of love for God.
