The Bible gives us multiple reasons why Jesus does not immediately take believers to Heaven once they are saved, despite them committing sin on Earth. Some of those reasons are listed below in no particular order:
He wants to teach them not to sin. Galatians 5:16-18 says, “But I say, walk by the Spirit, and you will not carry out the desire of the flesh. For the flesh sets its desire against the Spirit, and the Spirit against the flesh; for these are in opposition to one another, so that you may not do the things that you please. But if you are led by the Spirit, you are not under the Law.”
He wants them to share the gospel so others can be saved. Mark 16:16 says, “And He said to them, ‘Go into all the world and preach the gospel to every creature.’”
He wants to make them more like Himself. 2 Corinthians 3:18 says, “But we all, with unveiled face, beholding as in a mirror the glory of the Lord, are being transformed into the same image from glory to glory, just as by the Spirit of the Lord.” Also, Romans 12:2 says, “And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.” And Philippians 1:6 says, “He who has begun a good work in you will complete it until the day of Jesus Christ.”
He wants them to glorify Him in every way. 1 Peter 1:15 says, “But as He who called you is holy, you also be holy in all your conduct.” Also, Colossians 3:23 says, “And whatever you do, do it heartily, as to the Lord and not to men.”
He wants to sanctify them. 1 Thessalonians 5:23 says, “Now may the God of peace Himself sanctify you completely; and may your whole spirit, soul, and body be preserved blameless at the coming of our Lord Jesus Christ.” Also, 1 Thessalonians 4:3-8 says, “For this is the will of God, your sanctification; that is, that you abstain from sexual immorality; that each of you know how to possess his own vessel in sanctification and honor, not in lustful passion, like the Gentiles who do not know God; and that no man transgress and defraud his brother in the matter because the Lord is the avenger in all these things, just as we also told you before and solemnly warned you. For God has not called us for the purpose of impurity, but in sanctification. So, he who rejects this is not rejecting man but the God who gives His Holy Spirit to you.”
He wants to mature and grow them in their faith and knowledge of Him. 2 Peter 3:18 says, “But grow in the grace and knowledge of our Lord and Savior Jesus Christ. To Him be the glory both now and forever. Amen.” Also, Ephesians 4:14-16 says, “As a result, we are no longer to be children, tossed here and there by waves and carried about by every wind of doctrine, by the trickery of men, by craftiness in deceitful scheming; but speaking the truth in love, we are to grow up in all aspects into Him who is the head, even Christ, from whom the whole body, being fitted and held together by what every joint supplies, according to the proper working of each individual part, causes the growth of the body for the building up of itself in love.”
He wants their lives to be a testimony to others so they will glorify Him. Matthew 5:16 says, “Let your light so shine before men, that they may see your good works and glorify your Father in heaven.”
He wants them to use their spiritual gifts to minister to others. 1 Peter 4:10-11 says, “As each one has received a special gift, employ it in serving one another as good stewards of the manifold grace of God. Whoever speaks, is to do so as one who is speaking the utterances of God; whoever serves is to do so as one who is serving by the strength which God supplies; so that in all things God may be glorified through Jesus Christ, to whom belongs the glory and dominion forever and ever. Amen.”
He wants them to do good works. Ephesians 2:10 says, “For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand so that we would walk in them.”
He wants them to follow His will. 1 Peter 4:1-2 says, “Therefore, since Christ has suffered in the flesh, arm yourselves also with the same purpose, because he who has suffered in the flesh has ceased from sin, so as to live the rest of the time in the flesh no longer for the lusts of men, but for the will of God.”
He wants them to love Him and others. Matthew 22:37-40 says, “And He said to him, ‘You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.’ This is the great and foremost commandment. The second is like it, ‘You shall love your neighbor as yourself.’ On these two commandments depend the whole Law and the Prophets.’”
He wants them to obey His Word. James 1:22-25 says, “But be doers of the word, and not hearers only, deceiving yourselves. For if anyone is a hearer of the word and not a doer, he is like a man observing his natural face in a mirror; for he observes himself, goes away, and immediately forgets what kind of man he was. But he who looks into the perfect law of liberty and continues in it, and is not a forgetful hearer but a doer of the work, this one will be blessed in what he does.”
He wants them to be godly, respectful citizens. 1 Peter 2:13-17 says, “Submit yourselves for the Lord’s sake to every human institution, whether to a king as the one in authority, or to governors as sent by him for the punishment of evildoers and the praise of those who do right. For such is the will of God that by doing right you may silence the ignorance of foolish men. Act as free men, and do not use your freedom as a covering for evil, but use it as bondslaves of God. Honor all people, love the brotherhood, fear God, honor the king.”
I hope this information helps you understand why Jesus does not immediately take Christians home to Heaven but desires to accomplish much in and through them on Earth.
