Over the decades of my life, I must have said these words untold times. Mostly to put regret to naught, but often to reinforce my current decision.
It's all too easy to second-guess yourself; to find fault with decisions you make and to criticize what you do in life, but don't do it!!! Being a Christian is about living a life for God and trying to follow Jesus in everything you do. Do the best you can, do it with love and prayer and FORGET ABOUT IT!
God will work things out to HIS GLORY, believe that because it's true!!! Here is but ONE example...
Galatians, Chapter 1 (World English Bible)
11 But I make known to you, brothers, concerning the Good News which was preached by me, that it is not according to man. 12 For I didn’t receive it from man, nor was I taught it, but it came to me through revelation of Jesus Christ. 13 For you have heard of my way of living in time past in the Jews’ religion, how that beyond measure I persecuted the assembly of God and ravaged it. 14 I advanced in the Jews’ religion beyond many of my own age among my countrymen, being more exceedingly zealous for the traditions of my fathers. (emp. added vss. 13f.) 15 But when it was the good pleasure of God, who separated me from my mother’s womb and called me through his grace 16 to reveal his Son in me, that I might preach him among the Gentiles, I didn’t immediately confer with flesh and blood, 17 nor did I go up to Jerusalem to those who were apostles before me, but I went away into Arabia. Then I returned to Damascus.
18 Then after three years I went up to Jerusalem to visit Peter, and stayed with him fifteen days. 19 But of the other apostles I saw no one except James, the Lord’s brother. 20 Now about the things which I write to you, behold, before God, I’m not lying. 21 Then I came to the regions of Syria and Cilicia. 22 I was still unknown by face to the assemblies of Judea which were in Christ, 23 but they only heard: “He who once persecuted us now preaches the faith that he once tried to destroy.” 24 So they glorified God in me. (emp. added vss. 23f.)
God's will, God's way, God's results!!! Live for God, Love for God, let the past be the past and rejoice in what God has done in your life. Thank you, Jesus!!! Amen and AMEN!!!!
