And further, my son, be admonished by these. Of making many books there is no end, and much study is wearisome to the flesh. Let us hear the conclusion of the whole matter: Fear God and keep His commandments, For this is man's all. For God will bring every work into judgment, Including every secret thing, Whether good or evil. (Ecclesiastes 12:12-14)
To fear God, you must first believe there is a God. To keep God's commandments, you must first have a love to know God's heart and His will for all people. Only then with love for God and love for your neighbor will you have a heart to keep God's commandments. Place your faith and your trust in the spoken words of the Father/Son.
Many Christians seem to focused on what they see as a faith requirement for salvation and go no further. They don't see a need to love God nor to walk in His ways, no need to imitate Christ. The Father and Son yearn for a relationship through this life and the next. Don't worry about salvation after death; pursue a walk with God in the present, and do your best to imitate Christ in this life. Peace, joy, and happiness is in the walk with the Creator today. In that walk with the Father/Son, trials will continue to come, but now, you will have a strong hand at your side. And that strong hand will carry you through this life and the next!
May you have a love and a joy to please the Creator and the provider of salvation through His Son! May you have a faithfulness that comes from the heart.
