The moment a person accepts Jesus as his or her Savior, a new life begins. This Christian Life is a life lived with the indwelling Holy Spirit. The Holy Spirit is given to every true believer at the moment of Salvation. The natural man is dead and the Spiritual man is born, by believing in Jesus Christ and being justified by faith in Him.
The Christian Life is a constant, never-ending war between the flesh and the Spirit. We are constantly exposed to things that could easily draw us away from God and make us commit Sins that the devil would love us to do. As long as you are on earth, you cannot escape this war. However, you can fight the good fight with the Power of Christ resting in you.
We have no excuse to fall into a pattern of sin, as we have the Holy Spirit in us and sin would grieve the Holy Spirit indwelling in us. Holy Spirit is the counsellor and comforter given to all believers by the Grace and Power of God. Christ was tempted on earth just like every other human being, but He overcame sin and never let evil overcome Him.
We who are Born Again by the Spirit of God have the desire to please God, but many times we fail. Though we will not be completely perfect on this side of Heaven, we should keep growing in good works and obedience. If you have no desire to grow in the Lord, you have a very good reason to examine whether your faith is real.
If you are a Christian, you definitely won't become sinless now on earth, but you should sin less and less and less, as you keep abiding and growing in Christ.
If you live an obedient life that often overcomes the flesh, you will eventually start enjoying the fullest life that God wants us to. Please note that real abundant joy and peace doesn't come by a problem-free life or massive wealth or any sort of worldly pleasure, but by submission to God's will and living a life that is pleasing to God.
The only war that results in true Peace is the War Against the Flesh, won not by our strength but by God's power. God never promised that the Christian life journey is going to be easy or happy always. But, He will provide us with His strength and grace to live a Christian life that is more of Jesus and less of the world if we seek Him.
Jesus has prepared a place for every true believer. In heaven, there is no pain, illness, hunger or pandemic. It is the safest and best place filled with the glory of God. This world is not our permanent residence. Our lives should reflect the fact that we can rejoice in any circumstance on earth because we have a rock-solid hope of being with God forever.
We are called to be heavenly minded and store up treasures in Heaven. We will be rewarded for every good work we do for God on earth. Every Christian is supposed to be a full-time missionary, glorifying God wherever they are. God needs Christians everywhere; in every legitimate workplace. When the world identifies that Christians are not all about amassing wealth and fame on earth, but rather in the business of pleasing God in everything, God will be glorified.

2 Corinthians 5:10 - For we must all appear before the judgment seat of Christ; that every one may receive the things [done] in [his] body, according to that he hath done, whether [it be] good or bad.
Revelation 21:4- And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away.
