Deu 26:11 And you shall rejoice in all the good that the LORD your God has given to you and to your house, you, and the Levite, and the sojourner who is among you. “When you have finished paying all the tithe of your produce in the third year, which is the year of tithing, giving it to the Levite, the sojourner, the fatherless, and the widow, so that they may eat within your towns and be filled, then you shall say before the LORD your God, ‘I have removed the sacred portion out of my house, and moreover, I have given it to the Levite, the sojourner, the fatherless, and the widow, according to all your commandment that you have commanded me. I have not transgressed any of your commandments, nor have I forgotten them. I have not eaten of the tithe while I was mourning, or removed any of it while I was unclean, or offered any of it to the dead. I have obeyed the voice of the LORD my God. I have done according to all that you have commanded me. Look down from your holy habitation, from heaven, and bless your people Israel and the ground that you have given us, as you swore to our fathers, a land flowing with milk and honey.

1 Timothy 6:17-18 As for the rich in this present age, charge them not to be haughty, nor to set their hopes on the uncertainty of riches, but on God, who richly provides us with everything to enjoy.
When God has made good his promises to us, he expects we should own it to the honour of his faithfulness. And our creature comforts are doubly sweet, when we see them flowing from the fountain of the promise. The comfort we have in our own enjoyments, should lead us to be thankful for our share in public peace and plenty; and with present mercies we should bless the Lord for the former mercies we remember, and the further mercies we expect and hope for. (Henry)
When we receive from the LORD, and give back to Him, it makes us rejoice. It is the proper response of a creature to his Creator, who has supplied him with all good things. The prayer described here shows that the giving was done with the right kind of heart. God not only wants us to give, but to give with the right heart. Right giving is done according to God’s Word Right giving is done within the context of a whole life of obedience. Right giving genuinely sets aside what is to be given unto the LORD. Right giving is not done superstitiously, Right giving is done with the expectation of blessing. (Guzik)
How can we not rejoice? When saved our sins were washed away, we were forgiven, redeemed, born again, and transformed. We were promised eternal life in heaven with God. We were given the Holy Spirit to lead, guide, teach, encourage, convict us of sin, and yield the fruits of joy, peace, gentleness, kindness, love, grace, mercy, generosity, hospitality, humbleness, and patience. Beyond this God blesses us with great and precious promises, godly wisdom, fruits of our labors, and material, financial, and relational blessings. How can we not rejoice?
Rejoice in the Lord always, again I say rejoice.
