Well, it's complicated. Some of us think we are already good enough. Some believe we are so evil that God could never love us. But God has told us the truth, and it is available to all willing to reason with Him. So, we must decide whether we can trust God, the only one who claims to have created us.
Our choices are; we can continue to believe we already are good enough; we can reason with God to see if He is the Creator, or we can give up trying to understand it and live life as it comes to us.
God has told us He created everything and that He created it to work together for good, "In the beginning God created the heaven and the earth." Gen. 1:1 and "And we know that all things work together for good to them that love God, to them who are the called according to his purpose." Rom. 8:28. Why should we believe that?
We can believe God and the Bible once we see how His love changes our lives. "And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment. And the second is like, namely this, Thou shalt love thy neighbour as thyself. There is none other commandment greater than these." Mk. 12:30-31. If we don't love both God and our fellow humans, we will not be able to follow Jesus into heaven, "Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me." and "In my Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you. And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also." Jn. 14:2-3.
God draws us with His love for us, "For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. For God sent not his Son into the world to condemn the world; but that the world through him might be saved." Jn. 3:16-17, and Jesus teaches us how to love, "A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. By this shall all men know that ye are my disciples, if ye have love one to another." Jn. 13:34-35. Our love of others, which comes from our belief in Jesus, changes our behavior because He asks us to live the fruit of the Spirit, "But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, Meekness, temperance: against such there is no law." Gal. 5:22-23.
Are we willing to treat others with the Spirit of love? Do we want others to treat us this way? Those willing to live the fruit of the Spirit are the people Jesus has called to follow Him into heaven.
