The First Step
The first step in putting good decisions info action is called repentance in the Bible. Psalm 7:12-16 says,
If a man does not repent, God will whet his sword; he has bent and readied his bow; he has prepared for him his deadly weapons, making his arrows fiery shafts. Behold, the wicked man conceives evil and is pregnant with mischief and gives birth to lies. He makes a pit, digging it out, and falls into the hole that he has made. His mischief returns upon his own head, and on his own skull his violence descends
That certainly does not sound like a happy life. That is an outcome to be avoided.
The Second Step
The first action of one who desires to live a happy life is to be born again (John 3:3-5). Everyone needs a fresh start, and that is what God provides in baptism (Acts 2:38; Romans 6:1-5).
This is the greatest of new beginnings because this is the beginning of your life with Christ, the source of life. Baptism is that moment when our life and Christ become intertwined (Romans 6:3; Galatians 3:26-27; 1 Corinthians 12:13).
Repentance and baptism are not the goal of faith, they are the beginning of faith. They are the beginning of the happy and blessed life. These are the markers of entrance into the Christian race.
Having been born again, we can begin living in and enjoying the Christian’s blessings.
Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places, even as he chose us in him before the foundation of the world, that we should be holy and blameless before him. In love he predestined us for adoption as sons through Jesus Christ, according to the purpose of his will, to the praise of his glorious grace, with which he has blessed us in the Beloved. In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace, which he lavished upon us, in all wisdom and insight making known to us the mystery of his will, according to his purpose, which he set forth in Christ as a plan for the fullness of time, to unite all things in him, things in heaven and things on earth. Ephesians 1:3-10.
