When I was a young one, I recall being afraid to swim. Yet, unknowingly my dad was not an average swimmer, but swam in the Quinnebaug River and deep ocean. I clung on to him crying. If you want to be successful in life then you must learn how to swim or you might drown, he'd say.
Often, the priest of the parish I attend reminds us that you must get out of the boat, trusting that God will save you if you start to sink, as did Peter. Trust is the beginning of finding your way in anything that you attempt to do in life. Knowing you have a safety net helps in all situations. Who is that safety net, makes all the difference.
Christ is that safety net in my life. If you push out into the ocean, eventually you will tire, and this is when you come to the realization that you are not alone and never were. Then and there, you find Christ in your life. He is the only one that can save you.
So venture out, unafraid and trusting because that is when you begin to live and go forward. He will be there to catch you if you sink, when you call out to Him.
Call out to Him, the only One who truely can make you whole. Most of us are sinking from our brokenness and failures of life. The cross that we must carry, whether of our making or not, is real and heavy at times. See (Matthew 11:28)
Your deepest hour may be your best hour when you "let go and let God." To swim, then, or to step out, you must first "trust in Him", as did Peter.
Proverbs 3:5-8 "Trust in God with all your heart, and do not exalt your own wisdom. In all your ways know wisdom. That she may cut a straight path for you; And your foot will not stumble. Do not rely on your own discernment, but fear God, and turn away from every evil. Then there shall be healing for your body and care for your bones." (The Orthodox Study Bible)
