Obviously we cannot bring offerings to God in the way that Israel were instructed to do under the Law given at Sinai.
The purpose of the Jews’ offerings was to support the Levitical priesthood.
There is no designated priesthood in Christ which requires support.
The tithes were used for the relief of the fatherless, the stranger and the widow as well as the priesthood.
What God requires of us is not our goods.
What he requires is our belief and obedience to the gospel of his Son and our service to one another.
We are to be merciful to others
Matthew 9:13 But go ye and learn what that meaneth, I will have mercy, and not sacrifice:
We are to be holy in our behaviour
Romans 12:1 I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service.
We are to love and do good to one another
1 John 3:16 Hereby perceive we the love of God, because he laid down his life for us: and we ought to lay down our lives for the brethren.
Romans 13:8 Owe no man any thing, but to love one another; for he that loveth another hath fulfilled the law.
Galatians 6:10 As we have therefore opportunity, let us do good unto all men, especially unto them who are of the household of faith.
Ephesians 2:10 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
Philippians 2:1 If there be therefore any consolation in Christ, if any comfort of love, if any fellowship of the Spirit, if any bowels and mercies, 2 Fulfil ye my joy, that ye be likeminded, having the same love, being of one accord, of one mind. 3 Let nothing be done through strife or vainglory; but in lowliness of mind let each esteem other better than themselves. 4 Look not every man on his own things, but every man also on the things of others.
We are to pray for others
1 Timothy 2:1 I exhort therefore, that, first of all, supplications, prayers, intercessions, and giving of thanks, be made for all men; 2 For kings, and for all that are in authority; that we may lead a quiet and peaceable life in all godliness and honesty. 3 For this is good and acceptable in the sight of God our Saviour; 4 Who will have all men to be saved, and to come unto the knowledge of the truth.
We are to do good works
Titus 3:8 This is a faithful saying, and these things I will that thou affirm constantly, that they which have believed in God might be careful to maintain good works. These things are good and profitable unto men.
We are to praise and thank God and give to others.
Hebrews 13:15 By him therefore let us offer the sacrifice of praise to God continually, that is, the fruit of our lips giving thanks to his name. 16 But to do good and to communicate forget not: for with such sacrifices God is well pleased.
We are to feed, clothe and visit others as we have opportunity
Matthew 25:31 When the Son of man shall come in his glory, and all the holy angels with him, then shall he sit upon the throne of his glory: 32 And before him shall be gathered all nations: and he shall separate them one from another, as a shepherd divideth his sheep from the goats: 33 And he shall set the sheep on his right hand, but the goats on the left. 34 Then shall the King say unto them on his right hand, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world: 35 For I was an hungred, and ye gave me meat: I was thirsty, and ye gave me drink: I was a stranger, and ye took me in: 36 Naked, and ye clothed me: I was sick, and ye visited me: I was in prison, and ye came unto me. 37 Then shall the righteous answer him, saying, Lord, when saw we thee an hungred, and fed thee? or thirsty, and gave thee drink? 38 When saw we thee a stranger, and took thee in? or naked, and clothed thee? 39 Or when saw we thee sick, or in prison, and came unto thee? 40 And the King shall answer and say unto them, Verily I say unto you, Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me.
I hope you find this helpful.
