I am also Catholic and love my church, I love that it is universal and I can go virtually anywhere on the planet and find a Catholic church and a local Catholic community.
To grow in faith and love there are some straightforward things we can do. The first is to develop a prayer life. Like any other relationship we can only learn about another person by spending time with them. You can start this is in very simple ways. It is good to aim initially to pray for 20 minutes a day. Chose a time of day that works well for you and when you feel at your best. Try and have a regular time so that it becomes a habit. There are lots of different forms of prayer. Asking God to answer your prayers are “petitions” but also just sitting in God’s presence is a very powerful form of prayer.
I would suggest that you buy a candle that you like and have a quiet place that you can hopefully pray every day, or most days. Light your candle as a way to recognize that you are setting this time aside for God.
Look up on your phone what the Catholic mass readings of the day are. You can read all of them or just the Gospel. After reading the Gospel, reflect on what you have read, if you like to journal, jot down anything that comes to mind.
Then reflect on the past 24 hours and thank God for experiences and people that you are grateful for.
Then think about what you might have done better and could have done that you didn’t and ask for forgiveness.
Then pray for anything in particular that you are concerned about, if anyone comes to mind during this time, offer them to God.
Then ask the Holy Spirit to come and pray in you and draw you closer to God. Sit quietly in God’s presence for as long as you want. It’s fine if your mind wanders just quietly bring your mind back to focusing on being within God’s presence (just like when you sit with a good friend). If to begin with you don’t feel any different or you feel bored or distracted don’t worry. This is not a sign of failure of any kind. Prayer is a gift from God so we have to make ourselves available and listen. Just make this time exclusively for God and wait on Him is prayer. Even if you feel no positive emotions (such as peace, joy, contentment) don’t worry at all. We don’t rely on emotions in the spiritual life, but on the will. And your will is with God. Love is an action and you are choosing God.
Just think of it as any love realtionship. When you sit with someone you love, it makes no difference if we are feeling down or happy, distracted or focused - we are still choosing to be with that person. Your relationship with Jesus is exactly the same. You cannot know someone if you never choose to be with them. The more you regularly chose to be with God the more grace you will experience.
Another form of prayer is praising God and if you like to sing or want to listen to Christian music or chant and find this helps, you can use this as part of your prayer time.
If you feel inspired in any way and feel Jesus is moving your heart, you can write it down. Over time, if you jot down your thoughts you will often find patterns and ways God is speaking to you.
Prayer is very simple but if you do this daily you will find your heart and life changing.
I often like to read books by my favourite saints and mystics during this time, if you want recommendations I would talk to someone at church who you can tell has a strong prayer life because of how loving they are - you can’t help being drawn to people who are close to God. There is a supernatural beauty there.
The Mass is the most powerful prayer, so regularly attending Mass will strengthen and develop your faith.
It’s important to be in a state of Grace to draw closer to God and be able to recognize God (in fact the desire for God is a prayer in itself). If you haven’t been to the Sacrament of Reconciliation for a long time, look up an Examination of Conscience on the internet and pray and reflect on it. Write your answers down if necessary. Then go to the Sacrament and be very honest with God. You will immediately see a difference in your prayer life because you have removed blocks.
Regular use of the sacraments: Holy Communion at Mass and frequently going to the Sacrament of Reconciliation will draw you into a deeper relationship with God. I would also join some kind of group at church so you know others who are also wanting a deeper, more meaningful spiritual life.
