Trying to do God’s will is the basis of all Holiness, is it as simple as that. All other things are secondary.
Among other things this means
Be kind to all, specially to those who might be evil toward you.
Be patient with all, specially with yourself, we are very weak and prone to fall, we must acknowledge this. God’s Mercy is actually the only thing we will have once we leave Earth to defend against God’s inexorable justice, however remember Jesus said if we are merciful to our enemies, God will also be merciful toward us.
Be humble, as no one can really command, unless they have learned to first obey.
Attend Holy Mass if you can, or at least see a live stream, once per week (doing spiritual communion).
Pray always, everyday, no matter how good or bad things are going, this is essential and often overlooked.
Have absolute confidence in Mary , beside Our Lord, no other Saint is as powerful as she is, also no one is closer to God than Her.
Trusting fully in God is a very powerful way to live our life on Earth, although we need God’s grace to do it and keep it, ask for it in prayer and God will give it, since this is always good and something every person will benefit from.
God Bless
