I do not know exactly what kind of possessions we'll get but I can imagine it'll be something we enjoy now only they will be indestructible and at maximum capacity. Think of having an iPhone that has seemingly unlimited memory and battery, break-proof screen, perfect coding with no crashes or errors, be as fast as lightning, and will never become obsolete.
As for crowns, I kind of see them as awards for specific achievements while on Earth. We'll end up casting them at Jesus's feet as an honor. Some with have more than one, some will have none.
Five Crowns of Salvation • Five Crowns
1) The incorruptible crown:
This is also called the imperishable crown. This crown is given to believers who faithfully run the race, who crucify every selfish desire in the flesh and point men to Jesus. God calls some people to do things that will require some sacrifice in the way they will live and conduct their lives. Some people may be called to be a missionary in a far off and poor country. They will literally be working for almost nothing in earthly terms. They will have to sacrifice the money,possessions and life style they could have had, if they stayed home in their own country. The Bible says,
“Know ye not that they which run in a race run all, but one receiveth the prize? So run, that ye may obtain. And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible.” 1 Corinthians 9:24-25 KJV This verse also implies that these people will also receive this crown for the sacrifices they were willing to make for God to successfully complete the call and mission God had called them to do. Basically run whatever race that God has set out for you and be the best you can be for God. Be willing to make whatever sacrifices there may be to successfully complete the mission that God has set out for you.
2) The Crown of Rejoicing:
To those who faithfully are witnesses to the saving grace of God and leads souls to Jesus. This crown has also been named the soul winner’s crown. It indicates here that God will be giving a crown to those who have witnessed to others and leading people to Christ. Telling others about the grace of God, telling others about Jesus, is the greatest thing that you can do for someone while here on this earth. When you help someone to be led to the Lord, you have just been used as a vessel of God. It says in the Bible,
“Ye are witnesses, and God also, how holily and justly and unblameably we behaved ourselves among you that believe:” 1 Thessalonians 2:10 KJV God will judge you by your willingness and desire to be used by Him to witness to others, not necessarily on how many actually get saved, because we are to water and He gives the increase. Christians can be used by God to try to lead others to the Lord. God can fit opportunities for you in your life to witness and work for Him if you allow Him to. Some could be your unsaved friends, family members or co-workers, etc. The Bible says it good here,
“For what is our hope, or joy, or crown of rejoicing? Are not even ye in the presence of our Lord Jesus Christ at his coming?” 1 Thessalonians 2:19 KJV
3) The Crown of Life:
Jesus says that He will give this crown to those who undergo severe hardship, testing, tribulation and/or physical death on His behalf. Probably being willing to die for your faith in God would be the ultimate sacrifice. It is the greatest act of courage and love that you can show God. Christians who have been martyred for their faith throughout history will not only be given this crown of life, but other rewards once they enter into heaven. The Bible says,
“Blessed is the man that endureth temptation: for when he is tried, he shall receive the crown of life, which the Lord hath promised to them that love him.” James 1:12 KJV God the Father will honour each ones trials and tribulations and thus will be rewarding them accordingly. Look at this verse,
“Fear none of those things which thou shalt suffer: behold, the devil shall cast some of you into prison, that ye may be tried; and ye shall have tribulation ten days: be thou faithful unto death, and I will give thee a crown of life.” Revelation 2:10 KJV
4} The Crown of Righteousness:
To those who love the appearing of Christ, who anxiously wait and look forward to the day when He will return for His saints. This crown is given to those who have lived a good and righteous life for God while living down here on earth. If you are a believer you have been made righteous before God the Father as a result of Jesus dying on the cross for all of our sins. This means that the righteousness of Jesus has now been imputed to you. It also refers to us living a good and righteous life for God the Father with what time we have left down here. There are Christians who are righteous before God the Father as a result of being saved, called Justification, through the blood of Jesus Christ; but they are not living righteous lives in their actions, words and behaviours, called Sanctification. There are some people that may be saved in God’s eyes, but still continue to do evil works that the unsaved would do. We all have our flaws, weaknesses, and certain temptations that we may struggle with. It is not perfection but direction that God is looking for. God just wants each one of us to choose to do the right thing when faced with certain temptations or choices to do something bad. When it is all said and done, these Christians will probably be receiving some of the greatest rewards that God can hand out once they enter into heaven. It says in the Bible,
“Henceforth there is laid up for me a crown of righteousness, which the Lord, the righteous judge, shall give me at that day: and not to me only, but unto all them also that love his appearing.” 2 Timothy 4:8 KJV To live a righteous life for God will really be worth your while as you will definitely be given this crown by God Himself once you enter into heaven.
5) The Crown of Glory:
This is the pastor’s crown and will be given to the ministers who faithfully feed the flock of God. This probably could also include preachers, teachers, Sunday School teachers, missionaries and all those who teach the Word of God in their respective ministries. This crown may signify the importance and sacrifices of bringing up others into the ways of God. God wants those who are saved to grow and learn as much as they can about Him, His Son and His Holy Spirit and to do that he uses mature believers who are willing to each others. The Bible says,
“The elders which are among you I exhort, who am also an elder, and a witness of the sufferings of Christ, and also a partaker of the glory that shall be revealed: Feed the flock of God which is among you, taking the oversight thereof, not by constraint, but willingly; not for filthy lucre, but of a ready mind; Neither as being lords over God’s heritage, but being ensamples to the flock. And when the chief Shepherd shall appear, ye shall receive a crown of glory that fadeth not away.” 1 Peter 5:1-4 KJV God can use you to teach and shepherd others. God shows you the extreme importance that He is placing on those who teach and preach the word. Being willing to teach and educate others after they are saved is one of the greatest things you can do for them this side of heaven.
