2045 Because they are members of the Body whose Head is Christ,89 Christians contribute to building up the Church by the constancy of their convictions and their moral lives. The Church increases, grows, and develops through the holiness of her faithful, until “we all attain to the unity of the faith and of the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ.”90 (Catechism of the Catholic Church)
It’s not the things that you do once in a while that make the biggest impact, but those that you do continuously and even sacrificially at times. If God puts something in Your heart, just put your blinders on and work at it with determination. Don’t look to the world for support, it’s more than likely that you won’t get it. It’s ok. God has given you everything you need to accomplish anything that He asks of you. Work at it, leave the results to Him.
