I am realizing that in life you have to be confident in order to take risks and make the right and hard decisions that come with living. Either find that confidence in God (which I strongly recommend) or find that confidence somewhere, based on personal convictions and knowledge. People will give you very much needed and sometimes unsolicited and not-so-needed advice. Some of these people do love you and have your best interest at heart. But always know that advice given is subjective and greatly dependent upon a number of subjective human experiences, characteristics, and viewpoints. Only God is omniscient (all-knowing) and has the ability to advise with no bias, or at least with a bias toward his ultimate will (Himself) which is always for our own and other’s greater good. If you want to be lost and confused in life, be a consistent people follower or pleaser.
This doesn’t mean be stubborn and not heed advice. For then you become foolish as the Bible says (Prov. 12:15, Prov 18:2, Prov. 1:7, Prov 28:26). This doesn’t mean turn to your own heart’s followings and desires, for we know that these can be deceitful (Jer. 17:9). But this means do turn to God to gain the confidence and direction to make life's hardest decisions. This means filter every human word, emotion, and action through the lens of God's truth.
I appreciate practicality, so here is one practical advice: God will not always come down with a loud audible voice to advise you and tell you to turn left or right, or give you a dream, etc. But peace, understanding, and God-given confidence, holy desires and ambitions can be signs. Don’t underestimate the power of God to burn a desire, a dream, a passion in you so bad that you have no choice but to pursue it. But don’t forget that both Satan (evil) and God (good) work through our desires. So how do you distinguish evil from good? Read your Bible. Pray. Fellowship. Be discipled by more mature men and women.
Last practical point about being confident and committed to a decision is to find peace. Last year I learned that peace is a very important attribute of God and a lot of times that’s all God gives us at critical points of our lives, especially when we have to make the “big” decisions. We all know God as the God of love, but in the Bible he is mentioned many times as a God of peace. Peace is as important as love. In short, if there’s no peace, most likely God is not in it or you are not in God.
