What advice would you give to someone who is trying to focus their joy and delight in Jesus and Jesus only? I know it sounds kind of silly but it's honestly something that I struggle with a lot
Constantly walking by the spirit. If you aren’t in the spirit, you are in the flesh. And those who are in the flesh cannot please God.
"For those who live according to the flesh set their minds on the things of the flesh, but those who live according to the Spirit set their minds on the things of the spirit" Romans 8:5
Now I pray every single day asking God for his strength to lead me on this narrow road following Jesus at every moment. I strive to live obediently to God at all times following all his commands. The moment you decide to push the world aside, you’ll notice how much Joy and peace will fill you. God is so faithful and he knows what you strive for. He knows your struggles. Reveal them all to Him and he will take over.
"But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law. And those who belong to Christ jesus have crucified the flesh with its passions and desires." Galatians 5:22-23
The more you push into God, the less and less you will focus your joy and delight in the world. The world will always throw you down. Our God will never.
