“Therefore, as ye abound in every thing, in faith, and utterance, and knowledge, and in all diligence, and in your love to us, see that ye abound in this grace also.”
2 Corinthians‬ ‭8‬:‭7‬

You can abound in faith- it means your faith can grow bigger and stronger, you can use your faith to produce greater fruits of the word, just like they did in Corinth and in Thessalonica:
“We are bound to thank God always for you, brethren, as it is meet, because that your faith groweth exceedingly, and the charity of every one of you all toward each other aboundeth;” 2 Thessalonians‬ ‭1‬:‭3‬
Notice, the description- their faith grew exceedingly, this tells how much time they would have spent with and submitted to God’s word, because after all faith comes by hearing the word: Romans 10:17
So growing your faith is easy and simple, just increase the time you spend with the word, listening, agreeing and submitting to the word and your faith would increase. Look at Peter, in his first meeting with Jesus, (Luke 5:4-6) he spent time explaining his situation before he finally submitted and had a good catch, the next time Jesus would give such an instruction (Matthew 17:27, John 21:6-7) he wasted no time submitting- he had spent time with Jesus, the word, his faith had grown. Be and do likewise.
