Galatians 5: 22-23
> But the fruit of the Spirit is love, joy, peace, patience, goodness, goodness, faith, meekness, temperance; Against such things there is no law.
God has decided to dwell in us and make our body his temple and room. He promised to pour into our hearts, his love, through the Holy Spirit. The Word of God confirms that the Holy Spirit dwells in us and that all the components of the fruit of the Spirit are within us. We understand then, that joy as a component of the fruit of the Holy Spirit is within each believer. Just believing innocently lets out the joy that is in our spirit, due to the Holy Spirit that dwells in us.
As we see in Galatians 5: 22-23, joy is one of the components of the fruit of the Holy Spirit. Therefore, we believers must manifest joy and enjoy life in Christ, since we are filled with the Holy Spirit of God.
We may observe it this way: joy is in the deepest part of the person who has accepted Jesus as their Savior, since joy is in that person's spirit. But if that person's soul (his mind, his will and his feelings) is filled with worries, negative thoughts, reasoning, doubts and disbelief, those negative things will become a kind of wall that will retain the flow of the fruit of joy That lives in it.
The apostle Peter said to put all our anxieties and concerns on the Lord (1 Peter 5: 7). Peter urged the believers of his day to the following: "Do not worry about anything, but let your requests be known before God in every prayer and prayer, with thanksgiving. And the peace of God, which surpasses all understanding, He will keep their hearts and their thoughts on Christ Jesus "(Phil 4: 6-7).
Keep your mind full of thoughts of happiness and joy, while trusting God, He will take care of all your problems.
Trust in God will help us experience the power of his strength. The joy of the Lord is our strength. We can live trusting that both the joy of the Lord and the power of his strength will help us enjoy the true life in Christ Jesus.
