Christians believe in lots of things.
We believe that the Bible is the very Word of God, without error in the original writings and is sufficient for all matters of faith and conduct.
We believe in the Trinity – that we worship one God in trinity and the trinity in unity, neither blending their persons, nor dividing their essence. For the person of the Father is a distinct person, the person of the Son is another, and that of the Holy Spirit still another. But the divinity of the Father, Sin and Holy Spirit is one, their glory equal, their majesty coeternal.
We believe in God, the Father almighty, creator of heaven and earth.
We believe in Jesus Christ, His only Son, our Lord, who was conceived by the Holy Spirit and born of the virgin Mary. We believe that he suffered under Pontius Pilate, was crucified, died as a substitutionary sacrifice for the sins of the world, and was buried. On the third day he rose bodily from the dead. He ascended into heaven and is now seated at the right hand of God the Father almighty. We believe that he will come again to judge the living and the dead.
We believe in the Holy Spirit, and his work of regeneration, conviction, sealing and sanctification.
We believe in the forgiveness of sins, in our justification by faith alone by grace alone, in our adoption, in the resurrection of the body and in the life everlasting.
We believe that the church displays God’s glory in redeeming at great cost a people for himself. As the church, we are to help each other grow up to become like Jesus and to make disciples of all nations. God accomplishes this through means like the preaching and teaching of the Word, prayer, the sacraments, church discipline, leaders, accountability, mutual encouragement, holy living, ministries of mercy, evangelism, missions and discipleship.
In short, we believe in lots of things.
There are other things we believe in as well. Like exercise. We believe it’s good for us, physically, mentally and spiritually. We believe the present pain of exercise always leads to greater future gain. We believe that we ought to do it regularly, and that we should actively schedule it into our busy lives.
Yet despite our strong beliefs about exercise, most of us never get round to exercising. Our believing in the truths of the Christian faith should never become like believing in exercise.
