You are blessed "with every spiritual blessing in the heavenly places in Christ" (Ephesians 1:3). Faith in the Lord Jesus Christ receives all the blessings of God. You need not beg God to bless you. You need not struggle and strive to receive God's blessings. They are yours to receive in Christ alone.
You may ask, what are those blessings? In the first chapter of Ephesians several of those blessings are mentioned. You receive God's love, grace, peace, truth, forgiveness, and wisdom, through the Holy Spirit. There are countless more blessings for you "not only in this age, but also in the age to come" (Ephesians 1:21). Receive all God's blessings in Christ.
You may ask, why would God want to bless me? Because of His love and grace in Christ, "to the praise of the glory of His grace" (Ephesians 1:6). Grace means that the blessings of God come to you as the gift of God in Christ. A gift cannot be bought nor earned. God's blessings are by grace alone in Christ alone.
You may ask, how can I thank God for all of His blessings? Praise God from whom all blessings flow! Praise is the expression of a grateful heart to God for all of His blessings in Christ. Worship is giving thanks and praise to God through our prayers and songs. Praise God, because you are blessed "with every spiritual blessing in the heavenly places in Christ."
