We are in a contract with Jesus, and it is called the new covenant. Being in real estate, I write contracts for people, and when it comes to my tenants, I enter a contract with them. Each of us has a duty to uphold; I provide a home, and they pay to stay there. However, when it comes to our contract with God, he provides for both sides! He does all the work, and all we have to do is honor him as our one and only God. He makes it easy. Don’t get caught up in details that are not there. Become clear in your mind that Jesus is your way to salvation, accept him, confess your sin, take the steps to baptism as a profession of your faith, and he will do the rest.
For this is the covenant that I will make with the house of Israel after those days, declares the Lord: I will put my laws into their minds, and write them on their hearts, and I will be their God, and they shall be my people. Hebrews 8:10
